New security feature

2026-06-03 - We have installed a long list of IP ranges used by web crawlers and bots. We deny them access from now on.
If your IP is associated with one of the major providers, however, it might match with those we deny.
The match is decided on behalf of the first two of the IP4 number's four parts.
You can click the link above and see whether you receive an error code instead of the Welcome page.
If so, please read here.

Sending requests by email has been possible and will continue to be,  see the instructions.
You can also try the old standard html form, no guarantees though.



This is now history:
On Fri May 29 midnight, the MSN searchbot had overloaded the web server, just like in a DoS attack.
It sent GET requests every two milliseconds. Basically they are out for grabbing everything pixeled, .png etc.
MSN isn't the only bot but none has ever been that aggressive; I've got evidence (logfiles) that MSN changed their tactics at that point of time.

Upgrades of Apache2 and PHP were necessary, the latter being a bit nasty.
I only hope the blocking code I inserted keep the bots out from the html pages.


Hope we now run with full functionality again.
