The curse seems to still work, my brand new "backup" server was
installed in a location between Baltimore and Washington DC this
week. A short time later, a nearby train derails. I think Murphy
following me. Remember, its not parnoia if people really are out
to get you 
It appears most providers have found ways to re-route around
the fiber break/fire in Baltimore. Physical diversity? Why bother,
it only takes a day to have techs patch around the cut. Some
individual customers still say they have problems, but generally
things seem much better along the easter seaboard.

Other providers may have also been affected, but I have no
information about the status of their network. The CSX and
Amtrack routes are the primary fiber routes through Baltimore,
so it was a crap shoot which provider got hit. Were they in
the Amtrack right-of-way or the CSX right-of-way.
The Baltimore Fire Department started removing train cars from
the tunnel this morning, but stopped when the fire flared up
again.
