[tor-relays] FYI: ISP's and blocked Authorities

[Sebastian Urbach]

Hi,

It seems to be the case that a few ISP's are not up to date and still using 
old IP's to block Authorities. That means if you are able to connect to 
just 1 or 2 Authorities but not to all of them your ISP could be one of 
those candidates.

I saw this behaviour in one case just today. Connectivity with Gabelmoo and 
longclaw was possible but no other Authority was reachable. Gabelmoo 
recently changed the IP and longclaw is brand new afaik. That ISP is 
clearly using an old list of IPs to block Tor for their VPS systems.

What makes it even worse is that this system was going to be a Non-Exit 
relay :-(

I will ask the operator for more details and the good/bad ISP page will be 
updated accordingly. If you can reach some Authorities (not all) and you 
are not getting indexed and measured (also you can't find your system on 
the Atlas / Tor site), this could be the reason why.
