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." ***Stefan Mititelu http://twitter.com/netfortius http://www.linkedin.com/in/netfortius
