Brits saw an Amazon Web Services outage last week with millions of companies using the platform.
The company said that the issue started at 12.45am PDT on July 16 (8.45am BST) and was resolved around 1.30pm BST.
A statement, AWS said: “Between 12:45 AM and 4:18 AM PDT, we experienced increased 5xx errors for CloudFront customers utilizing VPC Origins connectivity.
“Our engineers were automatically engaged and immediately began investigating the root cause. By 2:57 AM PDT, we identified the root cause of the issue as an internal constraint on the fleet that manages connections to private VPC origins.
“When this constraint was reached, the system responsible for distributing routing configuration to our network processors failed to load the updated configuration data correctly, affecting routing of VPC Origin connections. At 3:52 AM PDT, we took multiple mitigation actions that led to full recovery at 4:18 AM PDT.
“Now that the issue has been mitigated, customers who temporarily changed their origin type can safely revert these changes. Customers utilizing other origin types were not affected by this issue. The issue has been resolved and the service is operating normally.”
