Yep.... it leads to:




Activity Type Code Desc: PROGRESS COMMENTS
Activity Type Code: PROG

OTDR readings were taken by AT&T West and a cut was located 1600 ft from
the San Jose, CA central office. AT&T West technicians are onsite
working to isolate the exact location of the cut. There are 4 cables
impacted. AT&T Mobility has 61 GSM and 45 co-located UMTS sites out of
service off of Santa Clara Base Station Controllers 15 & 23, and Santa
Clara Radio Network Controller 4. E911 has 52 Location Measuring Units
down. The AT&T West Santa Cruz 11 central office (41,803 ATNs) is
experiencing an SS7 isolation and the San Martin central office (11,904
ATNs) lost it's umbilical and is isolated at this time. The Bailey
remote site (4,973 ATNs) is also isolated. Scott's Valley has 3 out of 4
SS7 links down. The Santa Cruz 01, Aptos, Scott's Valley, Felton,
Boulder Creek, Ben Lomand, San Jose 11, San Jose 13, San Jose 21 central
offices have trunks impacted such that all lines are busy and incoming
calls are receiving trouble messages. The Santa Cruz County SO (178,040
ATNs), Scott's Valley PD (12,007 ATNs) and the UC Santa Cruz PD (14,909
ATNs) are all without ALI at this time. The Gilroy PD PSAP and the
Morgan Hill PD and CDF have been rerouted with ALI/ANI. The Felton CDF
has not been rerouted. There are 17 DSLAMS and 4 ATMS out of service
impacting DSL service. There are 3 SMDI Links down impacting voicemail
service. Verizon's Morgan Hill and Gilroy central offices are currently
isolated. There have been 224,865 blocked calls.

That AT&T has stopped provisioning protection fiber for automatic restoral is mind boggling.

That our crack (or on crack) govt contracting/emergency-preparedness staff didn't demand protected facilities for 911 is another mind boggling issue.

That there is no over-under wide-area back-up coverage for the cellular canopy ...

We posture and orate about being prepared for terrorist attacks and natural disasters, and then events like these reveal the reality:
   The emperor has no clothes.

Service to South Santa Clara county is completely down: Internet,
landline, and cellphones.  Both Verizon and AT&T are affected.  911 is
also down.

My cellphones show one or no bars.   Normally they are all four bars.

The idea that all of that is lumped in one fiber bundle is mind boggling.

I saw my Sonic.net-over-AT&T ADSL go dark at 02:30 local and it is still
down, served on a fiber remote out of SNCZCA01. (I'm guessing the 200 Paul outages are associated with where this ATM terminates and that's the cause, rather than the service in/out of Santa Cruz County, but I have no way of
telling which from here)

My own Gatespeed.net microwave to Equinix SV-3 is working fine (no surprise there), and I'm not seeing significant routing problems in/out of there with
transit or peering. (Not even any down peers, so no inter-Equinix-site
outage apparently).
