SOLVED – Unavailability of Woody, TinyGPU and TinyFAT; partial unavailability of other HPC systems

original source:

The Tier3 throughput cluster Woody as well as TinyGPU and TinyFAT are currently (since 2022-11-14, 15:15) not available due to large-area network failures on the campus. Other HPC systems are partially impacted, i.e. if individual compute or login nodes mounted file systems from one of the unavailable campus areas.

Update 2022-11-04 @ 17:30: Network connectivity seems to back as far as our clusters are concerned, though we have no final confirmation from the networking colleagues yet.
