We lost several of our GigE links to AT&T for 6 hours on 11/19, anyone else see
this and get a root cause from AT&T? All I can get is that they believe a change
caused the issue.
We lost several (but not all) of our Optiman circuits on 11/19 at about 10:20am. We were
told the root issue was that all VLANs in one of their switches had been accidentally
deleted / removed. We were never able to get any additional detail (like "how")
but services were restored about 16:45.
+1 to the above - we received the following RFO, from the their NOC:
"All impacted VLANS were rebuilt to restore service. It is believed
there were some configuration changes that caused the VLAN troubles. A
case has been opened with Cisco to further investigate the root
cause."
Sounds like a VTP mishap.
