Customers experienced intermittent WiFi connection failures on iOS Real devices in our US-West-1 & EU-Central-1 Data Centers, leading to increased error rates.
One of 4 DNS servers in our data center was upgraded and put back into rotation resulting in DNS resolution failures for hosts querying that host. The root cause was a misconfiguration in the routing table for that node.
We fixed the misconfiguration in the routing table.
We are adding more testing and monitoring for these types of changes.
