We have received following email bellow from Comcast
" We will be upgrading the ROMMON on our Denver router on the 26^th of August at 0100MDT/0700MDT. This will take down your BGP session for a short time while the line card reboots. Please leave your BGP session up so as to expedite restoration of service"
FDCServers expects no downtime for our customers as all of the traffic will automatically fail over to other carriers but we still like to keep everyone informed
