There will be a total site outage for Chameleon on Monday, October 19th, due to maintenance on the power system in the data center. While we don't expect the outage to take all day, we are blocking out a wide time slot just in case. During this time, users will be unable to access Chameleon resources.

We will have a short maintenance window at CHI@UC this coming Thursday, September 3rd, from 9AM-10AM, to do some maintenance to our core networking equipment.
During this time, instance launches on CHI@UC may be unreliable. The Jupyter interface will still be operational, and connectivity to existing instances should not be affected.
