Problems with Opensuse Mirror

There are currently problems with our mirror of opensuse.

Since June 08, it has been having problems staying up-to-date.

This is caused by infrastructure problems on opensuses end - their main upstream server delivers abysmal transfer rates to us. Unfortunately, transfer rates of about 2 Megabytes per second are not really enough to keep in sync with the rate of changes that opensuse has.

Unplanned Outage on June 03 [solved]

On June 03, 2020, at around 16:15 local time (14:15 UTC), disk accesses on ftp.fau.de became extremely slow. Less than an hour later, any attempts to access the disks with the ftp-data on it failed.

While the failed controller could temporarily be brought back by a powercycle at around 18:00 local time (16:00 UTC), it failed again within 10 minutes of booting the machine.
