Denial of Service attack

You may have encountered Service Unavailable" messages when trying to access the website today. There currently seems to be a denial of service attack going on, specifically against the old forum that's still used for internal communication by me and Elli.

The server log file shows a lot of requests with the user agent ClaudeBot. I currently assume that a misconfigured bot is the culprit of the attack. I moved the forum to a different folder and hope that this will already solve the problem. So far, it looks promising.
