The GSLB fail-over that was supposed to take place for the affected
services (that had configured their applications to fail-over) failed.

I heard about this the day after Google announced the Compute Engine
addition to the App Engine product lines they have. The demo was awesome.
I imagine Google has GSLB down pat by now, so some companies might start
looking... ;-]
