Howdy, folks...
I'm currently only able to mirror 5.5 without ISOs due to disk space constraints on my mirror server, but it's public, and offers good connectivity inside of Romania.
Locale: Bucharest, Romania HTTP via http://mirrors.sykotik.org/pub/centos/ FTP via ftp://mirrors.sykotik.org/pub/centos/
We've got 1gbit to ilink in Bucharest, who has very good uncapped connectivity inside of Romania, but we're capped at about 10mbit for international traffic.
Sponsoring organization is sykotik.org, and I'll get you guys a banner once we have one.
Thanks, Matt
