We have gigE to Level3 in Orlando, and saw something happen
around 1pm today. Customers were complaining of latency and
packet loss, and our traffic to/from L3 dropped noticably if
only for a few minutes.
It sounded like based on Craig's post yesterday they
did have some known issue and were working to resolve
it around that time, ~8 pm EST. I turned our gig link
to them back on around 4 AM EST and have not had any
complaints so far today. Traffic is up compared to
yesterday afternoon too, back where it would normally
be. The tech I spoke to this morning said he had no
knowledge of any issues yesterday, of course my ticket
also had none of the information I sent in to them
yesterday or even a clear description of what the
problem was....
Most likely the issue was communication between the NOC and the service management center. The NOC deals with the core facing events versus the SMC which takes the incoming calls from the customers. In this case the issue was identified and resolved in the NOC.
Perhaps the RFO was not posted internally or whomever you talked with didn't check the status updates or something. Lot's of things could have resulted in a tech not knowing about this type of issue.
Anyway, to tie up loose ends, there was a problem on a core router that was isolated and then repaired in Atlanta.
Some infrastructure blocks are not routed to portions of the network but should not affect ultimate reachability as long as the correct loopbacks and directly connected networks are advertised properly.
