We are currently investigating this issue.
Beginning April 21, a subset of Cloudflare Access customers experienced intermittent HTTP 500 errors on authentication requests. Impact is limited to a small percentage of requests in specific geographies. Service authentication requests are seeing the highest share of the errors. Cloudflare engineering is progressing a corrected rollout under tighter monitoring.
Exclaimer engineers are currently investigating a problem where signatures are being applied to messages even though a signature is already present on the most recent message. The issue does not appear to be impacting all mail at this time. We will provide more information as it becomes available.
We're having some issues with authentication and data synchronization delays for the Linear integration that will continue throughout the weekend. The engineering team is already working on a fix, which is estimated for early next week.
