(Completed) Extended Maintenance Notice
June 2nd, 2022, 4:35 AM
This maintenance has already been successfully completed.
There will be an extended maintenance period taking place sometime between 9PM Friday (6/3) and 6AM Saturday (6/4). This maintenance period is expected to take up to 3 hours, but may be longer. During the maintenance period Protochroma will be inaccessible, and may occasionally throw error messages instead of the downtime page.

Depending on the outcome, growing creatures may be credited for lost time. There may also be intermittent errors after the maintenance period has been completed. The site will be actively monitored throughout most of the day so that any issues are addressed as quickly as humanly possible.
