Comcast is on my list today for a different reason. We have Comcast Business Class service at one of our FL locations.<p>Tuesday we could not access VNC nor our remote database services from that location. All port 80 traffic was fine.  I had one of the staff call, wait on hold for an hours.<p>Just as I suspected Comcast had implemented port blocking on a high priced business account.  It took the guy a second to release it.  It put our company down for two to three hours.<p>Also the speed of Comcast service drops to 15-20% of advertised from 2:30 to 5 PM when kids arrive home from school.<p>Once the contract is up we are moving the service to someone who understands &quot;business class&quot;
