SGA is down

SGA or Siena Galaxy Atlas is down again but I’m getting this message.

504 Gateway Timed Out

@dstn or @ioannis, Are you planning for the new set of galaxies? Are they doing maintenance? Or is my internet down? Would the SGA get fixed?

It seems to be caused by an outage at the NERSC file system.
I’m currently accessing the SGA by using the Wayback machine.

HPSS is unrelated.

I just had to restart the web front-end.

Hello, It’s working for me. What is the SGA and the whole site run on which supercomputer centre that runs on NERSC? I thought it runs on Cori compute system.

The viewer and sga sites both run on the “Spin” service at NERSC, which is separate from Cori or Perlmutter. The files are all stored on the “community filesystem” (CFS).
