So I went to bed last night with my Apache webserver working fine, and I wake up to a bunch of people telling me they can't reach my website, spootur.com.
The way this is networked is a bit weird. It's inside a college network, but is accessible from the outside because it uses a public IP. The strange thing is that I don't get any error when accessing the site from inside the network, but anyone outside of the college network receives the 502 error.
I didn't change anything on the server since I went to bed (it was working fine then). Any idea on what could be causing this? Also: I'm only using the default Apache mods
