17:30 UTC - Our team has rate-limited additional sites experiencing high volumes of traffic and site performance has returned to normal for the NA region. We will continue to monitor to ensure performance remains stable. Our engineers are working on adding rate limiting at the API level, which will add an additional layer of protection for sites in the future.
16:22 UTC - Initial analysis indicates a significant increase in traffic across a subset of sites, resulting in degraded performance in our NA region. Automated rate-limiting measures were triggered and have since stabilized the affected services. Our team is continuing to investigate the underlying cause and monitor system performance.
15:57 UTC - Our system team is investigating slow response times in NA region. We will update this post once we have more information. Thank you for your patience.
