It appeas that both of our links to BT dropped, at the same time (02:06:51), including BGP with BT. All lines went off line. This lasted several minutes until 02:14:37 before lines stated coming back.
BE lines unaffected, of course.
lines all back. We'll chase up for an explantion in the morning. very odd.
I bet it is some sort of planned work they failed to bring to our attention.
I was just about to do the LNS switch over, but that will happen slightly later this morning now.
Logs confirm this was not a clean shutdown of BGP.
Hmm, timing different on each link. On the backup it was 02:06:44 to 02:14:21
It looks like this was caused by a BT PEW. We are chasing BT to confirm this though.
BT confirm this was due a PEW.
