No automatic e-mails were sent after the release started Friday evening. The service was restored at 22:00 CET on Saturday November 2nd.
This applies to all automatic e-mails sent from the system, like notifications and reminders.
The automatic e-mails will not be re-sent, so some users may not have gotten the expected e-mail notifications. Some notifications may be available in the notification center in Inspera Assessment, depending on your notification settings.
