We have an MPLS backbone from Level3 and are experiencing issues between
two of our San Francisco Bay Area locations – namely our HQ in Burlingame,
CA and our Savvis/CenturyLink Data Center in Santa Clara, CA. Ping
response times between these 2 sites are within the normal range, but our
Applications are timing out. We’ve obviously done a ton of troubleshooting
on the Application side of things, but everything points back to a circuit
issue and after a lot of testing we are scratching our heads trying to
narrow down this issue. So I wanted to post to this list to see if anyone
else has noticed issues with their Level3 circuits in the Bay Area over the
last 2 days as well?
Thanks for your feedback!
Regards, Leah

Hello Leah,
Yes and no, not anymore.
From Monday to Wed we had bad connectivity from LA to Sacramento, but different from your scenario, ping had a good latency but package loss was noticeable.
After 2 days of phone chattery we managed someone to skip San Jose, San Francisco and the whole SF Bay area, routing us via Fresno-Modesto to reach Sacramento. Latency increased a bit but overall quality was restored.
So yes, somehow I can confirm there's something going on with apparent isolated issues on Bay Area, specially near San Jose. Seems isolated because from what I noticed on phone it was "only me". And now you.
