We have contacted our data center and they are aware of a network issue that exists between Comcast and one of their bandwidth providers, Global Crossing. They are currently trying to track down the source and hopefully resolve the issue soon.
This only appears to affect some Comcast users and includes disruptions in receiving email and not being able to access some Laughing Squid hosted websites.
If you are one of the customers affected by this, understand that everything is functioning normally on our end and that your sites are viewable and your email will return to normal after this problem has been identified and resolved by these providers.
UPDATE: This issue was resolved by the multiple bandwidth carriers involved on Friday afternoon. Everything should be functioning normally at this point.
