When I try to access facebook.com I keep getting "page cannot be displayed , what is the problem here ?


Facebook uses https as its protocol once you have logged in. If other websites (such as Google, Yahoo, Amazon, etc.) work but websites such as Facebook, online banking, and others do not, then it seems that there is a problem with the security settings of the web browser since it would appear that the problems are only with websites that use secure HTTP (which is what the https protocol provides). Presuming that you are using Internet Explorer (as I have found it to be the most commonly used browser when this problem occurs), what you need to do is reset your security options back to defaults. You accomplish this by going to the Internet Options control panel applet or go to Tools'Internet Options from the pull-down menus within Internet Explorer and then click on the Security tab. You will find four icons at the top of the window for that tab: Internet, Local Intranet, Trusted Sites, and Restricted Sites. Click on each in turn and make sure that each has the Default Level button greyed out. If the Default Level button lights up for one of the options, click on it to reset its settings. After this, click on the Advanced tab and then click on the button toward the bottom that is labelled "Restore Advanced Settings." After this, click OK and close all windows of Internet Explorer that you currently have open. Wait about 30 seconds (to insure that all active Internet Explorer processes close out of memory) and then open Internet Explorer again and try to go to Facebook. If all goes well, you should now be able to get in.

I hope this helps. Let me know if I can assist you further.

Bandwidth Explained!


Most hosting companies offer a variety of bandwidth options in their plans. So exactly what is bandwidth as it relates to web hosting? Put simply, bandwidth is the amount of traffic that is allowed to occur between your web site and the rest of the internet. The amount of bandwidth a hosting company can provide is determined by their network connections, both internal to their data center and external to the public internet.

Network Connectivity

The internet, in the most simplest of terms, is a group of millions of computers connected by networks. These connections within the internet can be large or small depending upon the cabling and equipment that is used at a particular internet location. It is the size of each network connection that determines how much bandwidth is available. For example, if you use a DSL connection to connect to the internet, you have 1.54 Mega Bits (Mb) of bandwidth. Bandwidth therefore is measured in bits (a single 0 or 1). Bits are grouped in bytes which form words, text, and other information that is transferred between your computer and the internet.

If you have a DSL connection to the internet, you have dedicated bandwidth between your computer and your internet provider. But your internet provider may have thousandsof DSL connections to their location. All of these connection aggregate at your internet provider who then has their own dedicated connection to the internet (or multiple connections) which is much larger than your single connection. They must have enough bandwidth to serve your computing needs as well as all of their other customers. So while you have a 1.54Mb connection to your internet provider, your internet provider may have a 255Mb connection to the internet so it can accomodate your needs and up to 166 other users (255/1.54).

Traffic

A very simple analogy to use to understand bandwidth and traffic is to think of highways and cars. Bandwidth is the number of lanes on the highway. If you are the only car on a highway, you can travel very quickly. If you are stuck in the middleof rush hour, you may travel very slowly since all of the lanes are being used up.
Traffic is very simply the number of bits that are transferred on network connections. It is esiest to understand traffic using examples. One Gigabyte is 2 to the 30th power (1,073,741,824) bytes. One gigabyte is equal to 1,024 megabytes. To put this in perspective, it takes one byte to store one character. Imagine 100 file cabinets in a building, each of these cabinets holds1000 folders. Each folder has 100 papers. Each paper contains 100 characters - A GB is all the characters in the building. An MP3 is about 4MB, the same song in wav format is about 40MB, the full length movie can be 800MB to 1000MB (1000MB = 1GB).
If you were to transfer this MP3 song from a web site to your computer, you would create 4MB of traffic between the web site you are downloading from and your computer. Depending upon the network connection between the web site and the internet, the transfer may occur very quickly, or it could take time if other people are also downloading files at the same time. If, for example, the web site you download from has a 10MB connection to the internet, and you arte the only person accesing that web site to download your MP3, your 4MB file will be the only traffic on that web site. However, If three people are all downloading that same MP at the same time, 12MB (3 x 4MB) of traffic has been created. Because in this example, the host only has 10MB of bandwidth, someone will have to wait. The network equipment at the hosting company will cycle through each person downloading the file and trasfer a small portion at a time so each person's file transfer can take place, but the transfer for everyone downloading the file will be slower. If 100 people all came to the site and downloaded the MP3 at the same time, the transfer would be extremely slow. If the host wanted to decrease the time it took to download files simultaneously, it could increase the bandwidth of their internet connection (at a cost dur to upgrading equipment).


Hosting Bandwidth

In the example above, we discussed ttraffic in terms of downloading an MP3 file. However, each time you visit a web site, you are creating a traffic, because in order to view that web page on your computer, the web page is first downloaded to your computer (between the web site and you) which is then displayed using your browser software (Internet Explorer, Netscape, etc. ). The page itself is simply s file in the example above (however, a web page is usually much smaller than a music file).

A web page may be very small or large depending upon the amount of text and the number and quality of images integrated within the web page. For example, the home page for CNN.com is about 200KB (200 kilobytes = 200, 000 bytes = 1, 600, 000 bits). This is typically large for a web page. In comparison, Yahoo's home page is about 70KB.

How much Bandwidth Is Enough?

It depends (don't you hate that answer). But in truth, it does. Since bandwidth is a significant determinant of hosting plan prices, you should take time to determine just howmuch is right for you. Almost all hosting plans have bandwidth requirements measured in months, so you need to estimate the amount of bandwidth that will be required by your site on a monthly basis.

If you do not intend to provide file download capability from your site, the formula for calculating bandwidth is fairly straightforward:

Average Daily Visitors x Average Page Views x Average Page Size x 31 x Fudge Factor

If you intend to allow people to download files from your site, your bandwidth calculation should be:

[(Average Daily Visitors x Average Page Views x Average Page Size) + (Average Daily File Downloads x Average File Size)] x 31 x Fudge Factor

Lets us examine each item in the formula:

Average Daily Visitors - The number of people you expect to visit your site, on average, each day. Depending upon how you market your site, this number could be from 1 to 1, 000, 000.

Average Page Views - On average, the number ofr web pages you e4xpect a person to view. If ypu have 50 web pages in you web site, an average person may only view 5 of those pages each time they visit.

Average Page Size - The average size of your web pages, in Kilobytes (KB). If you have already designed your site, you can calculate this directly.

Average Daily File Downloads - The number of downloads you expect to occur on your site. This is a function of the numbers of visitorsand how many times a visitor downloads a file, on average, each day.

Average File SIze - Average file size of files that are downloadable from your site. Similar to your web pages, if you already know which files can be downloaded, you can calculate this directly.

Fudge Factor - A number greater than 1. using 1.5 would be safe, which assumes that your estimate is off by 50%. However, if you were very unsure, you could use 2 or 3 to ensure that your bandwidth requirements are more than met.

Usually, hosting plans offer bandwidth in terms of Gigabytes (GB) per month. This is why multiples them by 31.

Summary

Most personal or small business sites will not need more than 1GB of bandwidth per month. If you have a web site that is composed of static web pages and you expect little traffic to your site on a daily basis, go with a low bandwidth plan. If you go over the amount of bandwidth plan. If you go over the amount of bandwidth allocated in you plan, your hosting company could charge you over usage fees, so if you think the traffic to your site will be significant, you may want to go through the calculations above to estimate the amount of bandwidth required in a hosting plan.

Good luck!

The following instructions are for blocking malicious and unwanted websites in all versions of Internet Explorer. If you are using Firefox or other browsers, you may want to consider another, much more advanced way, to block websites using a host file: Use a Hosts File in Windows. Here is the easiest and most effective method to safely surf the Internet through IE.
1)Open Internet Explorer. In the Menubar click Tools ? Internet Options ? Content. In the Content Advisor box, click Enable.
2)Click the Approved Sites tab. Enter the address of the website.
Keep in mind - if you want to block the complete website put * in front. For example to block myspace completely, type *.
Click Never and then OK.

3)Click on the General tab and make sure to selectUsers can see websites that have no ratings
4)Enter a password you can remember easily with a hint.
5)Click OK to safely surf the Internet.
6)Microsoft uses the Family Online Safety Institute for the rating service. You can customize and see if that fits in your need.Consider installing web filtering software which allows or disallows websites based on their content.

I cant enter hotmail it says http 400 Bad Request


hi.

Cause The 400 Bad Request error is an HTTP status code that means that the request you sent to the website server (i.e. a request to load a web page) was somehow malformed therefore the server was unable to understand or process the request.

Resolution
  1. Check for errors in the URL. The most common reason for a 400 Bad Request error is because the URL was typed wrong or the link that was clicked on points to a URL with some kind of mistake in it.

  2. Though it's rare, the 400 Bad Request error could be an issue with the web site's server that you are trying to access. You may want to attempt to contact the webmaster or another site contact and inform them of the error message. The webmaster of most Internet sites can be reached via email at webmaster@website.com, replacing website.com with the actual website name.

I keep getting gateway error 504 all the time. help please


hi,

Resolving 504 errors - general
This problem is entirely due to slow IP communication between back-end computers, possibly including your Web server. Only the people who set up the network at the site which hosts the Web server can fix this problem.
Resolving 504 errors - CheckUpDown
Use of proxies and caching is increasing on the Web. Our CheckUpDown robot will always try to 'drill through' to the real computer that actually hosts your Web site, but we do not have complete control over where our HTTP request actually ends up. If only one link in the chain of computers dealing with our HTTP request is broken, then an error such as 504 can easily occur.
Please contact us (email preferred) whenever you encounter 504 errors - there is nothing you can do to sort them out. We then have to liaise with your ISP and the vendor of your Web server software so that they can review the flow of IP data traffic between various computers under their control. However this is not an easy error to sort out, because the ebb and flow of Internet traffic makes this type of error very transient.

please submit your rating to help me improve my statistics...

Thanks and regards...
