A massive Amazon Web Service outage brought down internet sites across the U.S. today.
Amazon has suffered brief outages before that have knocked offline services including Instagram, Vine, XERO. Its effects are widespread due to just how many services especially smaller ones rely on Amazon.
The outage appeared to have begun around 12:35 pm ET, according to Catchpoint Systems, a digital experience monitoring company. Operations were fully recovered by 4:49 pm ET, Amazon said. The Seattle-based company did not comment on the cause of the outage.
The most common causes of this type of outage are software related, said Lydia Leong, a cloud analyst with Gartner. “Either a bug in the code or human error. Right now we don’t know what it was.”
The outages brought down numerous websites that rely on Amazon’s hosting services. Alexa, Amazon’s person assistant used on its Echo, was reporting problems, as were websites Quora, Giphy and Trello, and numerous apps.
Last October, a massive cyber attack brought down major websites such as Amazon, Twitter, Reddit, and Spotify. No suspects have been named in the attacks.
