Hi. Sorry (again) about the downtime! I'll give everyone a quick explanation of what happened.
Earlier this month, we went down for a day or so because someone downloaded the same PDF file over and over again until my bandwidth allowance was completely used up. My hosting company was very helpful and reset the quota for me. Things were running fine until a few days ago when someone (probably the same person) did exactly the same thing again. The hosting company was, understandably, not willing to reset me quota a second time, so over the limit we stayed. Everything reset itself today so we're back to normal now.
I'm working on ways to avoid having this happen again in the future. I have put a couple changes in place now to make it more difficult to take the site down like that and I'm hoping that will be enough. I'm not going to detail exactly what I've done in case there are bad people reading this. In any event, my fixes aren't exactly perfect. So if there are any sysadmin types here with ideas, I'm happy to hear them. Ideally, I'd like an automated way of preventing the same IP address from downloading excessive amounts of data in a short period of time. I'm not sure how to go about doing that via cpanel, though, so I'm open to suggestions.
In tangentially-related news, I now own earthnotaglobe.com as well, so if anyone has ideas about what to do with that domain, I'm all ears.
