I had the same issue for months, not just in SE, it's just a general problem with network storage, it's crap - thankfully I have a workaround for my use case
I gave up with network storage, my use case is better handled by the KoboldCpp template which downloads the model each time - a 15-20 minute start up process is now 5-8 minutes at most
This is getting worse and worse again - there's a bit of availability in the morning European time, but by midday they're just gone, across all regions, every day, it seems to be when the US wakes up
This is not quite as bad as it was previously, but still going on, normally they all disappear evening European time (which is generally when I want to use it)
