We will be completing the upgrade of our Authentication System Servers and migrating and upgrading the Database Servers used by the Authentication System. During most of this maintenance window, the access to Zwift servers won't be possible. Users should avoid riding into that maintenance windows because besides riding alone it won't be possible to save or upload your activity while the maintenance is in progress, and existing sessions may get invalidated after the upgrade.
