Underlying network configuration issues encountered during maintenance are resolved and the systems are back in service. 

----

The network maintenance on Delta encountered an issue with the network that was discovered at final checkout.  The Delta login nodes will be available but could become unavailable at any time. The maintenance reservation will prevent the scheduler  from running jobs.  

----

Delta and DeltaAI users,
ALL Delta and DeltaAI services will be down next Wednesday, 6/18, from 7AM to 7PM central time. 

NO Delta or DeltaAI services will be available during the outage including: logins, computes, data transfer nodes, Open OnDemand.

During the outage the core high-speed network will have a software upgrade and reconfiguration to fully integrate the last compute hardware added to the system into the proper intended configuration. This upgrade will address some underlying issues in the network fabric to improve its performance and reliability, but does not include software changes on the clients so is expected to be transparent to users.
