    The Postmark UI availability was restored February 1st at approximately ~8am EST. We experienced an infrastructure issue that caused the UI to be unavailable for an extended period. This did not impact sending. We have identified the issue and remediated it. We are also working on improvements to our alerting to ensure a more timely update to our customers. We do not anticipate further issues.
