Monitoring
We continue to observe normal accessibility to the app and APIs. The full window of impact was from 4:12PM to 5:07PM (US Eastern). Any delayed messages from that time window have been sent. Most API calls (excluding Identify calls) made in that time window responded with failure response codes. Additionally, signup form submissions did not succeed, and any users of the signup forms received an error message in the form prompting them to try again later.
We will continue to monitor our systems.
