We have never had a xconnect fail, ever.  And we have several.  This is over a 6 year period.

	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?
