Recent SQL Error Messages

[Jefecinco]

For the past few days I get an SQL message when attempting to use the site. I second try always works. Any idea if it's me or the site?

The problem is only on the forum, as the rest of the website works fine. I have been out of town for several days, and I just got back. I will look into solving it.

UPDATE: I have found a temporary cure for the problem, but I will have to investigate further to really fix it.

Still working on this problem. It seems like it is caused by a malicious denial of service attack.

UPDATE: I am still working on this problem with help from my service provider.

At this moment, Sunday, March 9, about 11 a.m. EDT, I just implemented a significant change. The immediate effect seems to have been positive. But I will have to wait several hours to see if the forum access has really improved.

UPDATE: I have implemented some measures to block traffic from particular participants who where making an enormous number of requests for forum pages, literally multiple requests per second over hours and hours of attempts. On the worst recent 24-hour period, literally millions of forum page requests from these participants were blocked. The result has been that the forum is not being overloaded, and page permitted (i.e., unblocked) requests are back to their normal volume.

The actions of what are detected as malicious attackers trying to access the website seem to be quite variable, and in the past day or two I have noted that for some short periods the firewall that protects the website from these attacks has been temporarily unable to process some requests due to overload. This situation usually clears up in a few minutes, so patience when encountering any delay in being able to access continuousWave.com will be much appreciated.
