Key resharing maintenance on subnet uzr34 (II subnet)

Scheduled for Oct 19, 13:00 - 13:30 UTC

Scheduled

Subnet `uzr34` (II subnet) will be briefly paused and restarted, in order to create a backup of the new tECDSA Secp256r1 (NIST P-256) master key.

As a result, subnet `uzr34`, which hosts the Internet Identity (II) canister, will be unresponsive for approximately 5–10 minutes. During this brief downtime:
- New II sessions cannot be initiated
- Existing sessions remain unaffected
- Dapps using II will continue to operate normally for logged-in users
