Availability is now counted from our own monitoring answers. Uptime Kuma knows
the figure, but the REST bridge in front of it only answers "healthy, yes or
no", and waiting for the bridge to grow an endpoint would have left the panel
without the number indefinitely. The sync already asks on a schedule; counting
the answers gives a percentage that is ours and explainable.
An unanswered check is not a failed one — the counter only moves when a real
answer arrived, so our monitoring going down does not become the customer's
outage on the one figure they are asked to trust. An instance nobody has ever
checked shows no availability rather than 100 %.
The downgrade path existed nowhere. Going down is not the mirror of going up:
it can ask an instance to hold more than the target plan allows. Smaller plans
are now listed even when they cannot be taken, with the obstacle in the
customer's own numbers — "you have 31 users, this package allows 10" — because
a greyed-out button that does not name what is in the way is the thing people
ring about. Storage is checked against the last real reading rather than the
contractual allowance, or anyone who once bought a large plan could never leave
it. The limit is re-checked in the action: a rule enforced only in markup is
not enforced.
And the smaller corrections from this round:
- The cloud tab carried a hardcoded "B" as the instance's initial, and the PHP
and MariaDB versions, which tell a tenant nothing they can act on.
- "EU — Serverstandort im Angebot festgehalten" under a label already reading
"Serverstandort" was two sentences saying nothing. It is the country.
- Support promised a reply "binnen 4 Std." with nothing behind it. What is true
everywhere else is an answer on the same working day.
- The actions column appeared even when no row in the table had an action.

The panel could not show the storage ring or the transfer trend because nothing
measured them. instance_traffic keeps one row per billing period — right for an
allowance, useless as a series — and storage consumption was never sampled at
all, so the card could only ever state what was sold rather than what is used.
instance_metrics holds one row per instance per day, written by the traffic
collector on the visit it already makes. A second scheduler entry against the
same Proxmox API would have doubled the load and the failure modes for no gain.
Disk usage comes from `df` inside the guest rather than from Proxmox's own disk
figure, which reports the allocated image: that would show every customer a full
500 GB from their first day.
The rule the whole thing is built on: a reading that could not be taken is not a
reading of zero. The disk columns are nullable and left untouched when the guest
agent does not answer, so yesterday's figure stands instead of the ring dropping
to empty — which would tell a customer their data had vanished. Missing days
stay missing in the series rather than being filled with zeroes, which would
draw an outage that never happened. Both are covered by tests.
