I was told they were doing scheduled emergency maintenance about 3:30PM

I got notification of their maintenance window, albeit with 24 hours notice.
Notice came in at 11:00GMT-5 yesterday, maintenance was scheduled for
00:00GMT-5 this morning.
That said, the notice said that the maintenance was in Phoenix but I got a
notice about my IPT circuit at 60 Hudson
I acknowledge sliding past the maintenance window, and we're seeing similar
bumps, 09:42 - 09:46 CST is most recent. This are with our Wisconsin and
Netherlands locations. They seem to be having a bad day all around.

My point is that a conduit capable of storing additional 10 guage
copper can, instead, store 10 guage fiber.
Or, if you assume a conduit without any extra space, upgrading to
PON is also impossible.
Sure.
We lost our peering with them in Baton Rouge (Houston) but not in Jackson

My hunch is that this is fallout and repairs from Juniper PR839412.
Only fix is an upgrade. Not sure why they're not able to do a hitless

Workaround is proper filtering and other techniques on the RE/Loopback to

Should an upgrade be performed? Yes, but certainly doesn't have to have
