I had to block 217.237.151.0/24 (cw?.M1.srv.t-online.de)
as proxy servers from that subnet were downloading
dumps at >200mbps for a quite long time.
I do not know yet what was that, as there were lots
and lots of threads for German articles archive.
If you think the block is irrational, please note.
I suspect some bug in caching software or
something like that..
