<ul class="sreweekly-outage">
<li class="sreweekly-outage">As two astute readers pointed out (thanks!), the Gmail outage I included in the last issue was from 2009(!). Oops. However, Google <i>has</i> been experiencing a series of outages and degradations this month, so I&#8217;m just going to pretend I knew that rather than that I forgot to check the date on the article.</li>
</ul>

<li><a href="https://s">s3 outage</a>
<ul class="sreweekly-outage">
<li class="sreweekly-outage">S3 had an outage in us-east-1 on September 14th. This one showed up as yellow on their status site, with the text below. Companies that depend on S3 probably saw impact as well, but I couldn&#8217;t find any status posts other than <a href="https://status.heroku.com/incidents/1285">Heroku&#8217;s</a>.<br />
<blockquote><p><tt>11:58 AM PDT</tt> We are investigating increased error rates for Amazon S3 requests in the US-EAST-1 Region.<br />
<tt>12:20 PM PDT</tt> We can confirm that some customers are receiving throttling errors accessing S3. We are currently investigating the root cause.<br />
<tt>12:38 PM PDT</tt> We continue to work towards resolving the increased throttling errors for Amazon S3 requests in the US-EAST-1 Region. We have identified the subsystem responsible for the errors, identified root cause and are now working to resolve the issue.<br />
<tt>12:49 PM PDT</tt> We are now seeing recovery in the throttle error rates accessing Amazon S3. We have identified the root cause and have taken actions to prevent recurrence.<br />
<tt>1:05 PM PDT</tt> Between 11:40 AM and 12:56 PM PDT we experienced throttling errors accessing Amazon S3 in the US-EAST-1 Region. The issue is resolved and the service is operating normally.</p></blockquote>
