During the incident window, Braintree merchants experienced elevated GraphQL API and client-side errors. Customers may have also been unable to complete Braintree-hosted checkout flows. Some merchants would have also experienced increased latency and timeouts for the requests to the Braintree Gateway API.
At 9:35 UTC, our engineers were alerted to a loss in Braintree API traffic. As we investigated further, it was determined that there was a large increase in incoming requests to Braintree’s network, which were passed to our load balancers. As a result of the increased volume, a portion of our networking devices experienced service degradation resulting in latency, increased error rates and timeouts for some merchants.
