Reported Outages

UPDATE: We've cleared the issues with power management and the CHI@UC site should be stablized. Please file help desk tickets if your individual instance is having trouble coming back online.

There will be a total outage for the CHI@UC site on Monday, July 19th, due to maintenance on the power system in the data center.

In addition, JupyterHub and Trovi will not be available.

Update: Service is restored. If you continue to see issues, please let us know via the helpdesk.

The Network Stitching feature on CHI@UC is currently non-functional.

No traffic will flow over stitched links, either new or pre-existing.  This will impact any experiment on CHI@UC that uses them.

It is caused by an upstream issue, namely a network outage at ANL affecting Chameleon-EXOGENI vlans 3290-3299.

Update: Service is restored. If you continue to see issues, please let us know via the helpdesk.

We're currently experiencing issues with experimental networks at CHI@TACC, which affects external connectivity to your bare metal instances via, e.g., SSH.

As of February 22, 2021 the path for stitable networking has been interrupted on the TACC side. The TACC site networking team is aware of this issue and is pursuing a solution.

ANL is performing maintenance of the underlying cluster that powers the Chameleon auth server. For some period between 12pm and 5pm, the auth server may be unavailable. This will affect logins to Chameleon sites and the Jupyter environment, but existing experiments will be unaffected.
