Capacity Block Watch
A recurring data report tracking when AWS GPU capacity blocks can actually start across regions, instance families, and block lengths.
Field notes
Capacity Block Watch records AWS Capacity Block start dates rather than relying on the current availability screen. Its first issue compares nine instance types across 11 regions, classifying offers as open, queued, or sold out against an eight-week booking horizon. The report identifies regional flexibility as a no-cost lever: on September 10, a seven-day H100 block began immediately in several regions but waited 47 days in Mumbai. The page also links selected CSV-backed figures and offers the fuller history by email.
