A small business in my city is experiencing difficulty related to their website. Sometimes the site will be up, sometimes it will be down. Sometimes it works on one computer while the other can't find the site at all. Sometimes the site will be found in Internet Explorer but not in Chrome (the two browsers they use). This is all within their own network (behind a firewall).
I have found the site up and down from my home and other locations. There really doesn't seem to be a rhyme or reason to the website status.
I'm working with the host provider (who is local, but use Rackspace) to resolve the issue. The provider made a move of offices, so I'm wondering if it's a problem on their side.
Caches have been cleared, Browsers reset. Any ideas?
