A message regarding last nightโs site outage
From 11:45 pm PST on August 22 through 6:00 am PST on August 23, several eBay sites and customer service platforms around the world experienced intermittent outages. These outages were the result of technical issues which occurred during regularly scheduled maintenance.
Weโve resolved the core technical issues and all eBay sites and customer service functions are up and running again, with near 100% functionality. We are now working to build additional safeguards into the maintenance process to prevent this from happening again.
Know that at no point during this incident was any personal information at risk.
Sellers that were impacted by this outage are covered by the protections in our site outage policy. We will provide impacted sellers with additional information regarding applicable credits in the coming days.
