Thank you cdbc. I believe it is related to the forum server as well.

Loading of the theme images takes an average of 8 seconds per image... for getting the editor page that I am currently editing in it was around 4.9 seconds per image. Either the server cache needs to be cleaned, some issue with the HD/drive cache, the server is under full attack for these images (a crawler is able to do that when configured wrongly or simultaneously used in tens/hundreds) or hosting got issues.

Confirmed from the UK, while other sites are OK. So it's definitely something nearer the server than the users.

Yes it is. Martin notified me about it last week, but at the times I checked everything was snappy. Until this morning.
I looks like some search engine is indexing us (not honoring the robots.txt)

Redirect the IP of that search engine to a page showing a "middlefinger"?

But every cup makes you faster.

After that maintenance, the server seems to be back to normal. :)

Most robots respect fail2ban  ::) ;D
May have to define a subrange /24, though, for the intrusive traffic.

When looking at some of the IP blocks, I noticed they all were owned by amazon. Some googling resolved in ClaudeBot made by anthropic.com.
I've blocked this bot from accessing this forum

Update:
In the past 15 mins, it got already 3283 times rejected

@Marc
One remark: based on your info I investigated a bit and it seems it is actually github's hubot. Github acknowledges that there may be some issues, since they are upgrading their systems. That fits with the time span from the recent responsiveness issues.

So it is one thing that we now have a responsive forum, but what about github?
Are we using it? (I thought not, we use gitlab, but I may be wrong)

Something funny: github is owned by Microsoft, but you had to block an Amazon range instead of an Azure range... :o 8-)

It reports itself as "Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1.0; +claudebot@anthropic.com)"

I don't think this one is related to github if you visit anthropic.com

I think this is related. You may want to implement some rate limiter if you value AI enough to gather our forum's information. That would also help mitigate the issue and is less intrusive. But I will leave that up to you. OTOH ignoring robots.txt is not a nice way to operate.
