All issues affecting email delays are now confirmed as resolved. Post-mortem to follow shortly.
Early on August 10th, mail processing queues started growing significantly, leading to incoming mails in Zendesk being delayed by up to several hours. Therefore, emails being delivered to the Zendesk platform where processed noticeably slower than normal, leading to, among others, ticket creation delays. The issue went on for about 4 hours.
This outage was related to a global outage of an external cloud storage service that Zendesk relies on for mail processing. As this was a 3rd party dependency, our Operations team were monitoring closely but the problem resolved as the external service recovered.
