Sometimes a slowdown isn't Frontier
- Sometimes a slowdown is an old-fashioned DoS. I went nuts tonight
trying to find out if one of the databases had corrupted or any of the
usual reasons why the server pegged at a very high CPU percentage.
It wasn't any of those things. Turns out it was actually traffic. I
traced it to a single IP that was hitting on one of our magazine sites
and my personal site, with multiple queries a second. The attacks are
on the only two sites referenced from the CNN articles I wrote.
What made this worse was one of the URLs being hit was a forms
processing URL, which was failing, and taking a lot of time to process
We traced the attacks to the Philippines. Of course, some savvy person
could have routed to the Philippines, but ya never know. In the
meantime, we've basically been down for the last few hours and I've
been building custom code and working with my excellent ISP
Prominic.NET to block it.
So, sometimes, if your site unusually sluggish, it might not be
Frontier. It could just be someone who's beating on your site.

Another scenario: emailing notifications of error pages without
making sure that you haven't emailed something similar in the past
few minutes or hours. That yields a twofer: a Web denial of service
can flood your email too.
