June 11th, 2021, 8:30 AM: Maintenance complete. Systems are up.
May 27, 2021: Datamovers addresses have changed to improve high bandwidth connectivity and cybersecurity. The new addresses are 188.8.131.52 for nia-datamover1.scinet.utoronto.ca, and 184.108.40.206 for nia-datamover2.scinet.utoronto.ca.
If you have jobs that need to connect to a software license server using an ssh tunnel through nia-gw (which actually resolves to datamover1 or datamover2), you may need to ask the system administrators of that license server to allow incoming connections from the new addresses above.
