Some ISPs blocking /b/?

A lot of people have been complaining that /b/ is down, me being one of them. Today I found out that /b/ isn't down, but that it's returning 503's from some ISPs. I.e. epic fail @ home, but PROFIT @ work.

It's not a DNS issue, I can ping the server, and the rest of 4chan is accessible from home. WTF is going on? It's almost like port 80 requests to the img server (66.207.165.181) are blocked.

Have you tried emailing moot? It might be he blocked your ISP from /b/ for like CP posting, spamming or other shit someone from your subnet has done.

potential big problem, but hardly anyone browses textboards anymore so... try somewhere else.

/g/ mabey?

Thx guys, will do.

Britfag here, im not being able to connect to /b/ either, can get through with a proxy though
