From time to time something on the new server runs amok. Ping then is still working, ssh login and all other I could think of is not. Most of the times everything comes backup OK after some minutes, but I had to reboot the server twice. And the last outage took MySQL down.
The weather is fine, I am sitting on my balcony, drinking tea, eating cookies and reading “Zero History” by William Gibson. So I will will not try to work this out just now.
Update (Oct 3 18:12):
I found the reason after thinking a lot about things that occur every 6 hours on my machine. Nothing – but then I filtered the access log of the server. A massive parallel scraping of web pages from one IP. I have blocked that IP now and am thinking about limiting the number of parallel connections of one IP.
Update again: Complained at amazon web services.
Update Oct 5: Reply from Amazon:

Thank you for your attention in this matter.

Terminated. This somehow gives me a mental image of a guy in trench coat and his face in the shadow of his hat leaving the scene….
