Resolved

Monitoring

CloudFlare is experiencing issues globally, see https://www.cloudflarestatus.com/

We use CloudFlare to serve array.js and this was failing to load for some end users, causing events to not be sent by these users.

We have disabled CloudFlare proxying and are now seeing event traffic return to normal levels and don't expect any further impact from the CloudFlare outage
