For all those having DNS issues post maintenance. Provided you have already successfully updated your A Record but are still having issues browsing to your page.
Windows:
Clear all browser cache and history (I am assuming most people know how to do this and that each browser is a little different)
Flush your systems DNS by doing the following:
Click on Start
Click on Run
In the Openline type in "cmd" without the quotes and click ok
This should have opened a window titled something like C:\Windows\System32\cmd.exe
at the C prompt (C:\) type the following:
ipconfig /flushdns
All IP services are typically considered dynamic but they all also have TTL's (time to live) associated with them. They range form 1 hour to 48 hours typically. For your DNS this will vary depending on a few things. When you updated the A Record. When your provider pushed the new A Record.
Hopefully this might help some people by clearing out local caches on their machines that are affecting the ability hit their sites.
