All,
Today I had yet another cross-connect fail at our colo provider.
From
memory, this is the 6th cross-connect to fail while in service, in 4yrs
and recently there was a bad SFP on their end as well. This seemes like
a high failure rate to me. When I asked about the high failure rate,
they said that they run a lot of cables and there is a lot of jiggling
and wiggling... lots of chances to get bent out of whack from activity
near my patches and cables.
Until a few years ago my time was spent mostly in single tenant data
centers, and it may be true that we made fewer cabling changes and made
less of a ruckus when cabling... but this still seems like a pretty high
failure rate at the colo.
I am curious; what do you expect the average reliability of your
FastE
or GigE copper cross-connects at a colo?
Never to fail? Seriously; if you're talking about a passive connection
(optical or electrical) like a patch panel, I'd expect it to keep going
forever unless someone damages it.
Or until someone pulls out the wrong cable (which has happened to me).
That's not a failure though. It's a disconnection. It happens but is
readily attributable to a cause.
Random failures of a single ports connectivity.... bizzare and annoying.
Whole switches? Seen it.
Whole panels? Seen it.
Whole blades? Seen it.
Single port on a switch or patch panel? Never.
