[outages] flapping issues reaching East Coast AWS

[William Kern]

the last monit failure/success pair was 14:34/36 Pacific

I would have expected more warnings around 15:00.

Because its 15:16 now, we seem to have at least gone longer than we did 
all morning. So that is promising!

I'll respond back if I see another failure.
