### Summary On 4 May 2026, some merchants experienced intermittent access issues with their webstores and Control Panel. During this time, some sites may have displayed a “We will be back online shortly” message. ### Impact The issue caused intermittent availability issues for some merchant webstores and Control Panel access. The impact was not consistent across all sites, and some requests may have succeeded while others failed. ### Root Cause The issue was caused by a sudden spike in automated crawler traffic, which created increased load on the caching layer. This prevented some new connections from being established and resulted in intermittent availability issues. ### Resolution The traffic pattern was identified, and mitigation was applied to reduce the impact of the abnormal traffic while maintaining access for legitimate crawler activity. ### Preventative Actions We have strengthened traffic protection rules to better manage sudden high-volume crawler activity. We are also continuing to monitor traffic patterns and refine platform protections to reduce the risk of similar disruptions.
