Upcoming Scheduled Maintenance
| Start | End | What is happening? | What will be affected? |
|---|---|---|---|
2017-03-23 (1000) | 2017-03-23 (1500) | NCSA Nebula Outage | Nebula will take an outage to balance and build a more stable setup for the file system. This will require a pause of all instances, and Horizon being unavailable. |
| 2017-03-28 (0000) | 2017-03-29 (1600) | Blue Waters maintenance | Due to maintenance of cooling infrastructure at NPCF, Blue Waters will down during this period. Cray will also take this maintenance window to perform some system updates at the same time. We do not anticipate any impact to LSST services. The NPCF will be precooled prior to the maintenance shutdown and the facility has sufficient to ride out the loss of main cooling. |
