hit around 1:41 a.m. PDT on April 21, disrupting the company's EC2 (Elastic
Compute Cloud) service.
At 1:41 a.m.,
Amazon's status dashboard said, "We are currently investigating latency and

A note on
Quora's site said: "We're currently having an unexpected outage, and are
working to get the site back up as soon as possible. Thanks for your patience."
"Reddit is in -emergency read-only mode' right now because Amazon is
experiencing a degradation. They are working on it, but we are still waiting for

fix the site as soon as we can."

because of this storage problem. We are currently setting up dedicated
servers with hard-wired storage."
Singleton also said:
"We use Amazon
EC2, and we recommend it because their truly on-demand server resources make it
possible to rapidly try things, fix things and innovate. Innovation speed is
important. We recommend Amazon because they have done the most to deliver -on
