CI timeouts: Cache expiry causes scheduled failures, not random flakes

A continuous integration (CI) job experienced a timeout because its cache expired after seven days, forcing it to re-run from scratch. This initial run, which took 311 seconds against a 300-second budget, populated the cache. A subsequent re-run passed quickly by utilizing the cache, masking the underlying issue of an insufficient timeout setting. The author suggests three questions to distinguish true CI flakes from apparent ones: verify if the work completed, identify differences between runs (like cache status), and compare the duration against the budget to detect scheduled outages.
