Our standard for buildd / porterboxen of a released architecture is:
- multiple machines (N + 1, N sufficient to handle the buildd / porter load)
- under warranty or post-warranty hardware support for the duration of their
use as buildds / porterboxen including through the LTS timeframe
- located in multiple geographic locations (EU and NA, ideally)
- hosted by different hosting partners, each providing high availability
(power, cooling, networking) and intelligent remote hands
- under Debian control and/or ownership; available & affordable
- redundant disks and power supplies
- out-of-band service processor with power management or equivalent
Not satisfying the fifth bullet is a minor concern in the case of s390x.

Indeed. The more redundnant sponsors, the less worrying is the concern.

That is our requirement, effectively. The mild concern has not blocked the
port from releasing. That said, the concern should be documented.
