Dear customer,

We would like to inform you about a planned system upgrade that may affect your use of Zivver.

Date and Time
The upgrade is scheduled for Friday, October 27, 2023. We will commence at 20:00 CEST and aim to be completed by 22:00 CEST at the latest. Please note that we have scheduled a buffer period until 23:00 CEST in case more time is unexpectedly required for the upgrade.

Reason
We are upgrading the version of our database engine. This update is essential to improve the performance and security of our database.

Impact
During the scheduled upgrade period, users of the Webapp and other Zivver clients will not be able to log in. If you use the Zivver SMTP Gateway for email sending, you may temporarily be unable to connect to the SMTP gateway via email clients or automated systems. Depending on the (automation) system used, emails may be returned with an error message. Some email systems will also attempt to resend the emails during a set period.

We understand that this may cause inconvenience and apologize in advance for any disruption. However, this upgrade is crucial to ensure the overall performance and security of Zivver.

If you have further questions or need assistance, please do not hesitate to contact us via support@zivver.com

Thank you for your understanding and cooperation.
