You're assuming that the outage was somehow related to the quality of
hosting (virtual server, instance management, etc).

In my experience with large website failures, some of mine and talking
to others at conferences and elsewhere, I can't recall one where the
servers HW performance / virtualization management were the root cause
(and only one that was intrinsically hardware-based, which was a
catastrophic storage failure and not server failure).  Configuration
management, inadequate testing of new software, systems management
error, DBMS throughput capacity, emergent software / architecture
failures are the usual culprits.
