Server was rebooted. Problem solved for now. Remember folks, when AARoads Forum is down, first check to see if AARoads itself is down - before you panic about the forum. Because the site won't be down for very long if it is.
Thanks,
I did check that and that's how I knew it was more than the forum. (I tried periodically from 3:30pm EST until 8:30pm EST until I could access it again.)
If one of us notices AAroads.com or the forum is down, should we email someone? If so, who at what address?
I noticed it from this afternoon onwards. I had problems logging into the control panel for the server as well, but as it turns out, they were doing maintenance on their control panels, so the timing led me to think it was an overall problem with the hosting company servers. Later on our cpanel started working properly again, and that is when I called and had the server rebooted.
