When a Glacier Cracks Like a Slow Query: Reading Permafrost Provisioning Warning Signs
Imagine a database query that should take two seconds. After an upgrade, it takes two minutes. The application doesn't crash—it just gets slower, then slower still. You check the execution outline. The index is gone. Fragmentation is high. The query is scanning every row. Permafrost under a builded works the same way. No collapse, no dramatic event. Just a gradual loss of bearing headroom, like a query that slowly stops using indexes. By the phase you see surface crack or door frames that won't close, the frozen ground underneath has already degraded beyond recovery. Here, the warn signs are thermal, not electrical—and they mimic the failure modes of a poorly tuned database. Who Must Decide, and When A community mentor says however confident you feel, rehearse the failure case once before you ship the revision.
