200 Paul Ave is seeing several carriers down. I am also in Santa Cruz and
cannot make or receive long distance calls on my land lines. Unconfirmed

Hello,
Mercurynews.com is reporting telephone outages in Santa Clara and
Santa Cruz counties that started around 2:00 am local time. I
observed numerous carrier outages starting around 4:00 am local
time. Does anyone know if this is due to the same fiber cut, or are
these separate issues?
Seeing the same thing have an oc48 down from abovenet out of 200 paul

down, served on a fiber remote out of SNCZCA01. (I'm guessing the 200

I still think skipping the securing of manholes and access points in favor
of active monitoring with offsite access is a better solution. You can't

Nope.
You never did say what the multiplier was. How many miles or detection

This all implies that the majority of fiber is in "tunnels" that can
