ATT, Comcast Issues
Did anyone experience issues with ATT and Comcast between 8-9:00 PM on 8/10 ?
There was also some talk about a fiber cut in bay area, but I could not find anything on
google about it.

ATT, Comcast Issues [ In reply to ]
I'm a Comcast subscriber in the bay, and I do pretty extensive
monitoring of Comcast IP connectivity/reliability (both incoming and
outgoing).

I witnessed no service interruptions on 2009/08/10 between 2000-2100
PDT, and my periodic traceroutes/mtrs show no indication of IP network
reconvergence that took place during that time frame. My IP tests do
not utilise Comcast<-->AT&T paths though, only Comcast<-->Level3 or
Comcast<-->Abovenet.

Packets from my Comcast connection to a destination in Santa Clara
normally go from Mountain View -> Oakland -> Sacramento -> San Jose ->
Santa Clara. This is visible in traceroute/mtr.

The best place to look for outage reports of this sort is on
BroadbandReports/DSLreports. The below lists are for general forum
discussion and direct Comcast-employee-to-customer support, respectively
(you won't be able to read the latter posts, but you can see the
Topics).

Additionally, my night job involves monitoring quite a few links in and
out of the Bay via different transport providers, and nothing was
witnessed with AT&T on the night of 2009/08/10.

Hope this helps.

I didn't notice anything out of the ordinary, but, this is the first
Month that Comcast has
been able to achieve one 9 of reliability since my service was
installed in January.

No, I'm not exaggerating, they literally are down ~3-4 days each month
until now.
Before you get too impressed, they have yet to achieve a second 9 of
reliability,
even this month.
