An upstream WAF provider is experiencing increased latency in the IAD region, which appears to be primarily affecting connections from AWS us-east to our API endpoints.
Most traffic has been rerouted to nearby regions, so siteverify endpoints from servers connecting from AWS us-east regions that do not use our PrivateLink or Direct Routing options may see 20-50ms of increased latency until IAD is restored.
Impact appears to be less than 0.005% of total requests, but may be concentrated on some network links.
