Update: This has been completed.
We'll be doing some server database maintenance starting Thursday, January 11, at 9PM PST, UTC+8. During this time, users will not be able to log in.
In order to avoid losing progress, you may want to plan on ending your ride before maintenance starts - or after it ends. While it's estimated this will happen from 9PM to 11PM PST, it's possible the schedule will change based on how it progresses. You can watch status.zwift.com for live maintenance updates.
Server maintenance affects all online users in all timezones. Here's a timezone converter if you're unsure of when this window occurs for you.
We'll be monitoring the situation closely and provide updates, both here and on status.zwift.com, if anything doesn't go as planned.
Thanks in advance for your understanding!
