Reported Outages

We will be performing unplanned maintenance on the JupyterHub server to address CVE-2019-5736. This is a critical security bug with the Docker container runtime. The JupyterHub server will be down for a few minutes while the updates are applied. Your existing Notebook servers should come back automatically once the maintenance is finished.

Update: this took a bit longer than expected, but the JupyterHub server is back up after the maintenance. Thank you for your patience.

UPDATE: The maintenance is complete and services have been restored.

REMINDER: Chameleon systems at TACC will not be available on 8 January, 2019. All instances will be powered off during this maintenance, so please make sure that your work is saved beforehand. 

Chameleon systems at TACC will be unavailable on 8 January, 2019 from 8:30 a.m. to 5 p.m. (CST). Scheduled maintenance will be performed during this time. CHI@TACC, KVM@TACC, and the Chameleon portal will be unavailable during this time.

Access to Chameleon systems at UC will be unavailable from 8:00 AM CST until 12:00 PM CST on January 7, 2019 to allow for the installation of a new network spine switch which will increase the networking capabilities at UC. This will affect CHI@UC and the Jupyter notebook environment.

Access to Chameleon systems at UC will be unavailable from 8:00 AM CST until 12:00 PM CST on December 10, 2018 to allow for the installation of a new network spine switch which will increase the networking capabilities at UC. This will affect CHI@UC and the Jupyter notebook environment.

Resolved: Work has been completed.

Access to Chameleon systems at TACC will be unavailable from 8:30 AM CDT until 1:30 PM CDT on December 9, 2018 to allow for upgrades to the TACC core network hardware. This will affect CHI@TACC, KVM@TACC, and the ChameleonCloud portal (https://www.chameleoncloud.org)

Update: Maintenance is complete. Thank you for your patience.

We will be conducting a networking services upgrade for the CHI@TACC site on Monday, November 26 starting at 10:00 AM CST, ending by 4:00 PM CST the same day. During this time the networking services of CHI@TACC will be unavailable, meaning that no new instances can be launched, and no changes to user-defined networking will be possible. Traffic to instances created on Skylake Compute nodes will be affected, but we do not expect any interruption to other instances.

UPDATE: Today's work is complete and services have been returned to normal.

We will be taking the Swift Object Store offline temporarily at CHI@UC on Tuesday, October 30th from 9:30AM until about 2PM CST for network maintenance. We will send out an all clear notice when the work is complete.

RESOLVED: The network outage for CHI@TACC has been resolved. If you continue to have trouble accessing your instances, please submit a ticket at https://www.chameleoncloud.org/user/help/

CHI@TACC is experiencing an outage for networking to instances. We are investigating the issue, and will update you when it is resolved.

We are experiencing a networking outage impacting Skylake nodes on CHI@UC. Deployment of new instances and connectivity to existing ones may fail. We are investigating this issue and will provide an update as soon as possible. Haswell nodes on CHI@UC can still be used successfully.

We need to extend today's power outage at UC into tomorrow. Estimated time is noon CST October 23.

We will be performing scheduled power maintenance on the CHI@UC site on October 22 starting at 12:00 UTC. This maintenance period is expected to last 24 hours. During this time all systems will be down. This means it will not be possible to create leases, update existing leases, launch instances, or connect to already-launched instances. The CHI@UC GUI will also be down at this time.
