Some of our Collaboration labs are undergoing quick maintenance today. Users will be unable to reserve the some of the collab labs today. Those undergoing maintenance have been temporarily removed from the catalog. If you already have a reservation in these labs, you will be unaffected.
We only expect the maintenance to last ~2-4 hours. We'll let you know when you can reserve these great labs again! Please let us know if you have any comments or concerns.
