This was a timely question, as we've have a GigE fiber line with them
for 6 months now.
Largely, the link performs at ~999Mbit 99% of the time  :)
However, we've had two issues with connectivity that seem to originate
from their network. The link will show up, but both sides of our fiber
will show 0 frames received, and lots of transmit errors. It takes a
call into the Comcast NOC each time for them to resolve it, but
they've been silent on what may actually be going on. These
interruptions last anywhere from 30 minutes, to the last one almost 7
hours (luckily over a weekend).

Benefits to this, being Metro Ethernet, they do support tagged VLAN's,
so cost to entry is low in terms of equipment and setup/support.

Our link goes between downtown Portland, OR, to across the river to
East Vancouver and Mill Plain.
