The reliance on a small variety of huge corporations to underpin the online is akin to placing all of our eggs in a tiny handful of baskets. When it really works, it is nice, however just one small factor must go incorrect for the web to fall to its knees in a matter of minutes.How widespread was the AWS outage?Just after midnight PT on Oct. 20, AWS first registered a difficulty on its service standing web page, saying it was “investigating increased error rates and latencies for multiple AWS services in the US-East-1 Region.” Around 2 a.m. PT, it stated it had recognized a possible root reason behind the problem.
