# **What happened** On September 11, between approximately 2:18 PM and 2:30 PM EDT, some Vimeo OTT users were unable to access video pages and applications, including admin and staff sites. The API was unaffected during this outage. # **What caused it** A recent update contained faulty logic, which resulted in a cascading error. This error consumed available resources and caused the outage. # **How we responded** Our internal monitoring systems detected this issue almost immediately. Our engineering team quickly identified the faulty update and reverted to a prior stable version of Vimeo OTT. # **What we’re doing to prevent a recurrence** We’re investigating why the code caused the cascading error. Once we have a better understanding of the underlying issue, we plan to implement safeguards in our code review process to reduce the risk of similar outages.
