cloud2.mikrotik.com not reachable?

Hello!

I backed up the config of my hex to the cloud for weeks successfully.
"/system backup cloud print" shows my the last backup from 2026-06-07.
I cannot delete old backups or make new backups.

Acc to Cloud - RouterOS - MikroTik Documentation the Backup should send data to cloud2.mikrotik.com

A Ping from to cloud2.mikrotik.com does not work from the hex's ISP. Neither v4 nor v6.
From another ISP in Austria a Ping to cloud2.mikrotik.com works via v4+v6.
A Ping from a third ISP to this destination also does not work.
A bit confusing.

Is there maybe a general routing issue? Or has the dest-server a problem?
