Dear Chameleon Users,

CHI@TACC will undergo a scheduled outage on Tuesday, August 18, 2026, lasting the day while we perform system upgrades.

  • Existing instances and leases will continue to run
  • Network access may be intermittent as upgrades are applied
  • Due to connectivity interruptions, consider CHI@UC or CHI@NCAR for time-sensitive or remotely monitored workloads

Thank you for your patience as we work to improve the platform. Please direct questions to the helpdesk.
