Remember the cloud outage last week that interrupted Thrillist emails, knocked Aviary’s site down for more than a day and lost some of Chartbeat’s data? Amazon posted a lengthy post-mortem explaining what happened (passive voice: “a network change was performed,” “the traffic shift was executed incorrectly”) and offering customers in the region 10 days free, regardless of whether they were impacted or not. “These customers will not have to do anything in order to receive this credit, as it will be automatically applied to their next AWS bill. Customers can see whether they qualify for the service credit by logging into their AWS Account Activity page,” Amazon said.
