Amazon cloud outage takes down Reddit and Quora

A failure affecting Amazon’s EC2 service in northern Virginia has downed a number of prominent sites, including Reddit and Quora.

At one point, FourSquare seemed to have been affected, however, the site appears to be back up now.

“We are continuing to see connectivity errors impacting EC2 instances, increased latencies impacting EBS volumes in multiple availability zones in the US-EAST-1 region, and increased error rates affecting EBS CreateVolume API calls,” the company confirmed at 2:49AMPT.

“We are also experiencing delayed launches for EBS backed EC2 instances in affected availability zones in the US-EAST-1 region. We continue to work towards resolution.”

Another status updated posted at 6:59 AM PDT reads:

“There has been a moderate increase in error rates for CreateVolume. This may impact the launch of new EBS-backed EC2 instances in multiple availability zones in the US-EAST-1 region. 

Launches of instance store AMIs are currently unaffected. We are continuing to work on resolving this issue.”

According to AllThingsD, the outage affected (whether slowdown or offline) multiple sites aside from Quora and Reddit, such as:

  • Hootsuite
  • Discovr
  • Wildfire
  • Livefyre
  • CampgroundManager
  • Totango
  • ESchedule
  • ZeHosting
Recorded Future
  • PercentMobile
  • Cydia Store

Some sites may already be restored.
