We host our status site on Heroku to ensure its availability
during an outage. However, during our downtime on Tuesday
our status site experienced some availability issues.
As traffic to the status site began to ramp up, we increased
the number of dynos running from 8 to 64 and finally 90.
This had a negative effect since we were running an old
development database addon (shared database). The number of
dynos maxed out the available connections to the database
causing additional processes to crash.
Ninety dynos for a status page? What was going on there?
