   We are continuing our work to fix this latency issue, which has been observed to impact clients connecting to Supabase Projects from the eastern United States. These clients may include servers and serverless functions located in that geographical region, regardless of the region in which the Project is hosted.

   A mitigation for this issue was applied earlier today, but we do not have sufficient evidence to conclude that the mitigation resulted in improvement to this eastern US latency issue. We have tied the issue to a particular PoP, and we are continuing to work with our networking partners to bring this issue to a final resolution. We will provide another update within 4 hours, if not before. We appreciate your patience.

   Identified

   Our networking partners have implemented a mitigation to the latency issue at the problematic PoP in the Eastern US, and we have since observed significant improvement in rates of high latency across the region. We are continuing to work with those partners to isolate any additional root causes of latency and improve the reliability of our networking infrastructure across the region.

   While we have observed significant improvement in rates of high latency, we note that some users are still experiencing issues during peak Eastern US business hours. We continue to work with our networking partners to isolate and resolve any lingering sources of high latency. We recognize that this is a longstanding issue and appreciate the patience of affected customers. We will continue to share additional updates here as soon as they are available.
