Routing issue to 12.183.19.0/27

[ccj2]

I can't access servers in the 12.183.19.0/27 subnet, nor can I access my server from the servers located in that range. I can access any other Internet addresses from either location though. I'm able to access both locations from my phone (T-mobile). I was last able to connect last Monday 3/4/2013. I'll be happy to provide more information privately if needed.
