downtime Help: Ever seen a 'Apache Test Page' Page while visiting an IAM/KLOV site?
Ok...
So I just took down the forums for the last two hours (actually, I just changed the firewall so no one could get to it).
I've been making a bunch of quiet but important changes to the site, and as a small part of it, I had to make some changes to the Apache web server configuration. I restarted the server and then, other than forums.arcade-museum.com, 6 other subdomains (like coinslot.arcade-museum.com) when brought up in my Firefox browser displayed (instead of the appropriate site), an Apache Test Page. This usually happens when Apache is misconfigured or can't access (permission denied) a particular folder. The test page is sort of a default folder, and I keep it around for testing/troubleshooting purposes. In short, I could see from Apache logs that the browser was connecting to the correct IP address. However it didn't look like it was requested the page correctly, or apache wasn't seeing the request correctly.
In the hour right before this happened, I made changes to Apache, to DNS servers, to scripts, to server network configurations... all potentially troublesome activities.
Except... I couldn't think of anything I did to cause this. I figured I must have a typo someplace. I didn't find anything though. Finally I tried other browsers. Um... everything worked except Firefox. Then other computers and an iPad. Ok.. everything worked everywhere except Firefox on my computer. I decided to clear cookies on the browser and then pages like
http://coinslot.arcade-museum.com loaded. So did every other subdomain that didn't work before.
Now coinslot.arcade-museum.com doesn't use cookies at all. It doesn't look at them, it doesn't set them. It doesn't care. But somehow some cookie was messing with the HTTP request to the apache server in a way in which the requested server name wasn't getting through properly. No idea why, but I basically took the forums offline for 2 hours for no reason other than prudence.
Any system admins have any ideas?
Has anyone here every seen an Apache 2 Test Page load here instead of what they are looking for?
Can everyone load
http://coinslot.arcade-museum.com/
BTW: My work computer is updated fully. I have current antivirus running and just did a Malewarebytes scan (found nothing, as expected).
All very weird.
