ITYM:
15 - Circuit has been re-mapped on the IP Network. We believe this has
resolved the fault. Please resolve the issue directly with your customer.
15 - Flex VC
I've had this resolution at least 6 times this year. Symptoms are that the
circuit syncs up fine, but the router just won't log in. Doesn't matter
what kit you put on it, it doesn't want to know. Turning up the debugging
on a Cisco attached to the affected circuit suggests that the exchange end
of things doesn't send LLC packets in time [ie it never sends them], so the
router never attempts to log in, so you get no connection. I thought at
first it was 21CN-related software upgrades at exchanges, but a) I can't
correlate these annoying outages with any publicly available information
about 21CN rollout and b) it's happened twice to two circuits now. Very
annoying, yet another fault to be blamed on the mysterious black box that
is BT. Most of the time our monitoring systems show that the circuit
disappeared in the small hours of the previous day, which is what makes me
suspect maintenance work BT are doing out of hours.
