    FYI- couldn't access the site a couple times this p.m. Error message was "Database error".

    Had a problem last night with the AddThis bot hitting the site several times a second for a few hours. I blocked the IP. I've been watching the load at home, so when it starts to spike, I can track down who's responsible that minute.

    The .htaccess deny file is growing by the day, with the increasing number of strange bots and spiders that consume bandwidth and processor time, but really don't bring any traffic to the site.

    The MySQL server went down a few minutes ago. I manually restarted it. Don't know what caused it, though.

    This a.m. seemed like the bad old days again. Database error, slow/non response, etc.

    Having problems with load spikes. Long lunch.

    Wonky again today. Meeting at 1 PM, so can't diagnose. I'll try tweaking httpd.conf when I get home.

    Playing around with different Apache (httpd.conf) settings tonight, and have an email off to tech support to see if there's anything happening on the node.

    Okay, some new server settings that the host thinks will work. Let's keep our fingers crossed.

    Load spiking despite no increase in traffic. Trouble ticket in. Trying a tweak to my.conf in the meantime.

    The server was running smoothly throughout the day, but we got a crazy load spike a short while ago, again with no increase in traffic.

    Host says we may need a bigger server. I don't believe them. Traffic has been steady for the past two years.

    I'll try more tweaks.

    Tweaking some MySQL settings tonight. There may be occasional database errors.

    Load mostly under 1.0 throughout the AM. Keeping my fingers crossed.

    Looks like we made it through lunch without a spike.

    A weird spike to 6.48 around 2:20. I'll check the logs.

    Okay, I think I got it.

    * Blocked a bunch of very aggressive bots, although I'm still having a hard time shaking Baidu, a Chinese search engine.
    * Got a tweaked MySQL configuration that ultimately survived a smoke test of sorts, serving pages (slowly) while the load was up around 60+. Seems a bit faster, too.

    Spike from a denial-of-service attack.
