We experienced an outage over the weekend of our disk image service and reservation service at CHI@UC. This would have affected any new leases and launching new instances, but existing network connectivity to running experiments would have continued as normal. We have as of 12:00PM CT restored the services to their original working order.

The CHI@TACC Chameleon site experienced a network outage starting at approximately 5PM CT. Connectivity to instances via floating IPs was affectected. While network services have been restored, some instances may have lost their DHCP IP address during the outage. Resetting those interfaces from the instances' console should restore connectivity.
