The maintenance planned for today (July 16) is partially complete.
* HTC users of ap2001.chtc.wisc.edu should be able to log in and submit jobs.
* HPC users can use the new login node (spark-login.chtc.wisc.edu) and submit jobs to the partitions available from that node.
* Access to ap2002.chtc.wisc.edu and hpclogin3.chtc.wisc.edu remains unavailable.

Impacts:
* Login to servers ap2001.chtc.wisc.edu, ap2002.chtc.wisc.edu, hpclogin3.chtc.wisc.edu and spark-login.chtc.wisc.edu will be unavailable starting on the afternoon of Monday, July 15.
* Jobs from ap2001 and ap2002, and on all HPC partitions will be interrupted as well. They should remain in the queue and re-run when the servers are back up.
This extended maintenance will address a bug that has likely been causing, among other things, the periodic unexpected shutdowns of hpclogin3, ap2001 and ap2002. We are also using this maintenance period for outstanding network updates.
