While we are continuing to see improvements for customer access to the Iterable web app and global API endpoints, customers may still experience an elevated error rate, timeouts, or degraded performance when accessing our services due to continued issues with our provider. Sends or Journeys that are delayed will be queued automatically on our end and delivered once all issues are resolved. There is no need to retry/reschedule them manually.

We are now also seeing issues connecting to the Iterable application itself. We are continuing to work through these network issues with our upstream provider to restore full access to our customers. Any scheduled campaigns or journeys are still being queued to our backend.
