Goes offline for no reason

Help! My computer is going offline often while searching for a page. I either get the message, "Cannot find server or DNS error Internet," or "Windows has detected a connection problem between the computer and the modem..." with the suggestion to go to Tools, check connectivity, internet options, etc. I've done all those with no improvement. Searches often take forever with the result the "Cannot find server" message. I have dial-up and am having a few other problems also which may or may not be related. But I never have a problem getting connected when I dial-up, and many of the times it apparently goes offline I am still connected. Thanks!

Assuming you have the latest updated spyware removal programmes and anti virus programmes and run a recent scan. It may be that you have some corrupt cookies etc. The first thing to do is clear temp files etc, the best programme for this is a free and spyware free programme called CCleaner which you can download from here and give it a software check and obsolete file cleanup. http://www.filehippo.com/download_ccleaner/

I am trying to get information for this url link https://sconent-ort2-1-xxfbcdn.net. if you can help? Thank you.

So why is it unavailable:
When you visit a website, the first thing that happens behind the scenes is the browser contacts the DNS server. Sometimes this DNS lookup can fail, which results in an ugly error message.
Your message might look something like this:
In this article, we're going to walk through the five most common ways to fix the problem so this message goes away and you can once again access the internet.
Steps you can use to help resolve the issue

Update your drivers

One reason you may be seeing the "DNS server is unavailable" or "server DNS address could not be found" error may be due to an incorrect, corrupt, or outdated driver. You can check on your driver either manually or automatically.
Manual driver update Go to your manufacturer's website and search for the most recent correct driver. If you have trouble finding it or not even sure what it looks, contact the manufacturer and they can get you what you need. You might need to check with both your PC's manufacturer and the manufacturer of the component itself.
Automatic driver update Download and install Driver Easy. It will scan your computer and tell you what drivers are missing or outdated, and then update them all for you. Just click on the "Update All" button to download and automatically install the drivers.
This is definitely the better option for the less tech-savvy, and pretty much does all the heavy lifting for you. Plus, it's free!

Clear Chrome's Host Cache

Sometimes Chrome's host cache can become either too full or even corrupt, which will block access to websites.This is another very common cause of the error message you're seeing, and luckily, it's easy to fix.
The first thing you'll need to do is to open up Chrome and type this into your address bar:
chrome://net-internals/#dns
Once you click Enter on your keyboard, you should see something like this:
You'll want to click on the button that says Clear host cache next to where it says Host resolver cache. Once this is done, refresh the page and check to see if the problem persists. If it does, continue reading for more troubleshooting tips!

Delete the Files in Your 'etc' Folder

This is another easy fix. Navigate to your 'etc' folder, which can be found at C:\Windows\System32\drivers\etc. Once you have found this folder, delete all of the files you find there. Be sure to close chrome after and then open Chrome again and try accessing a website to see if this fix solved the issue.
More detailed solutions!

Change Your DNS Server Settings

The issue of "server DNS address could not be found" error could be due to your actual DNS servers and how they are configured. To check that they are in fact configured correctly, press the Windows logo key on your keyboard and R at the same time to prompt a Run command.
Next, you'll want to type Control Panel in the text box and click OK. This will open up your Control Panel.
View by Small icons, as indicated in the above screenshot, and click on where it says Network and Sharing Center. Then, you'll click on Change adapter settings over on the left side of the screen. From there, right click on either the Local Area or Wireless Network Connection icon and go to properties.
You'll now see a list of items the connection is using. Click on Internet Protocol Version 4 (TCP/IPv4). Once that is selected, click on the Properties button. You'll see a General tab. If Obtain DNS server address automatically is not selected, then select it and click OK. If it is already selected, select Use the following DNS server address instead and click OK.
The Preferred DNS server should read: 8.8.8.8 and the Alternate DNS server should read 8.8.4.4.
Now check to see if this resolves the issue.

Renew and Clear Your DNS

When using Windows, it by default will automatically store the IP addresses of websites you visit. This allows them to load faster when you visit them. Sometimes this cache will be corrupt or outdated, but you can simply renew and clear it.
The first step is to open your Run box again by hitting Windows and R simultaneously on your keyboard. Then type cmd in the text box and hit ctrl + Shift + Enter to open up the admin Command Prompt.
While this might look a little unfamiliar, especially for the less tech-savvy, all you have to do is type ipconfig /flushdns and hit Enter on your keyboard. This will flush out your cache in the case that it's outdated or corrupt.
Next, type ipconfig /renew and hit Enter again. Last, you'll want to type ipconfig /registerdns and press Enter one more time.
And that's it! Reboot your system and check to see if the issue has been resolved. Hopefully, one of these troubleshooting tips hit home and was able to get rid of the DNS server error message.

My girlfriends pc suddenly stopped connecting to the facebook site, she was on it one day and it cut her off and suddenly from her pc she can't connect to any pages of facebook. no login page no homepage...

I have notice this problem to as well. Last week especially, what facebook said, "That they was under going maintenance and taking some of the servers offline. Now this week I am having no trouble. There are several reasoning here. The first step is to try disabling your fire wall on your computer. Secondly, try cleaning the cache under the tools options and click on Internet Options. Then you click on clean cache memory. If that doesn't work try rebooting your internet connection either your dsl or cable internet by unplugging it for 30 seconds and plugging it back in.

Oops! This page appears broken. DNS Error - Server cannot be found.

The servers are located in the network by using it's ip address.
Using names for the domains is easier for humans.
A Domain Name Server (DNS) keeps track of the server ip address related with the domain name.
When an error occurs finding the corresponding ip address for the domain name, youll get the message "Oops! This page appears broken. DNS Error - Server cannot be found.".

  2. The DNS server listed for your ISP configuration is not working.
  3. The web site is offline.
  4. The DNS server settings for your internet configuration are wrong.
Possible resolutions:
  1. Try a different Web Address, see if it works

  3. Check you IP address configuration settings and ensure that auto-assign DNS is selected (Default setting)
