Monitoring
From approximately 4:20am to 5:30am, 10:40am to 11:10am and 12:55pm to 1:50pm PT on August 27th, a subset of our servers in the European region that serve the api.mixpanel.com/track API endpoint served 503 errors. Applications using Mixpanel's native mobile libraries queued events locally and automatically retried sending events until successful. Other Mixpanel libraries do not have automatic queues and could have experienced data loss.
We are investigating possible data recovery methods for the event data that was lost during these times. Updates to this incident will be made by 6pm PT on August 30th, 2017. We truly appreciate your patience and apologize for any disruption.
