As the WSJ reports:
Large electrical storms on the east coast disrupted power for
Amazon.com Inc. cloud-computing operations Friday night, causing outages
for customers such as Netflix Inc. and photo-sharing service Instagram.
The Seattle-based online retailer operates data centers with servers
that manage the Web operations of many other companies, a practice often
called cloud computing. Power outages caused by catastrophic storms
that blanketed the east coast affected Amazon's operations in Virginia.
On Saturday afternoon, Amazon was still reporting performance issues
for what it calls its elastic cloud compute, relational database and
elastic beanstalk services. The problems appeared to have begun
appearing on the site at around 11:21 p.m. EDT on Friday.
For those old guys like me who had built global networks on their own nickle, this was always a risky business. There was just a storm, guys, not an asteroid. You should have planned for that. Secon exits, Plan B, whatever! I have seen them all...
Prior planning prevents poor performance ... my father always said that to me!
