Always Free E2.1.Micro stuck in Processing after reboot migration window ended

Summary:

An Always Free VM.Standard.E2.1.Micro instance in ap-singapore-1 remains unreachable after its required reboot migration window ended. The maintenance event is still stuck in “Processing”.

Content (please ensure you mask any confidential information):

The maintenance event shows:

• Maintenance category: Required
• Instance action: Reboot Migration
• Status: Processing
• Scheduled window: 2026-09-09 22:24:34 UTC to 2026-09-10 22:24:34 UTC
• Reschedule allowed: True
• Delete local storage: False

The instance lifecycle state still shows RUNNING, but SSH does not complete its handshake and HTTPS is unavailable.

I attempted both a normal reboot and a diagnostic reboot. Both operations were rejected with:

“instance is currently being modified, try again later”
