FOC uploads on calibration net failing — provider selection and replication issues #615

Description

@HavenCTO

Is calibration net still supported? Providers are either failing to complete uploads entirely or failing the SP-to-SP replication pull for the secondary copy. I've had to drop to 1 copy and exclude specific provider IDs just to get uploads through.

By default, synapse-sdk stores 2 copies: one "primary" provider that the client uploads bytes to, plus a "secondary" that pulls from the primary via SP-to-SP transfer. The client upload only goes to the primary — if that primary is down or flaky, the whole upload throws StoreError: Failed to store on primary provider N and nothing commits. I've seen this specifically with provider 4 (caliberation-pdp.infrafolio.com) being selected as primary and failing at the store step's network request.

On calibration net, provider availability is inconsistent enough that the default 2-copy replication frequently fails at either the primary upload stage or the secondary SP-to-SP pull stage. This makes the network essentially unusable for development without manual workarounds.

The ask: Can calibration net providers be looked at? Either get the flaky ones back online or remove them from rotation so auto-selection stops picking dead providers as primary. Right now the default settings are broken enough that uploads just don't complete.
