GitHub introduces price limiting for Actions cache entries at 200 uploads per minute per repository, addressing system stability issues from high-volume uploads.
GitHub has carried out a brand new price restrict on its Actions cache system, capping uploads at 200 new cache entries per minute for every repository. The change, introduced January 16, 2026, targets repositories that have been hammering the cache system with rapid-fire uploads and inflicting stability issues throughout the platform.
Downloads stay unaffected. In case your workflows pull present cache entries, nothing modifications. The restrict particularly targets the creation of latest entries—a distinction that issues for groups operating parallel builds that generate contemporary cache knowledge.
Why now? GitHub cited “cache thrash” because the offender. Repositories importing large volumes of cache entries briefly bursts have been degrading efficiency for everybody else on the shared infrastructure. The 200-per-minute cap offers heavy customers sufficient headroom for legit use instances whereas stopping the type of abuse that was destabilizing the system.
A part of a Broader Actions Overhaul
This price restrict arrives amid a number of vital modifications to GitHub Actions economics. Earlier this month, GitHub diminished pricing on hosted runners by 15% to 39% relying on dimension. However the greater information hits March 1, 2026, when self-hosted runner utilization in personal repos begins costing $0.002 per minute—a brand new cost that is pushing some groups to rethink their CI/CD structure totally.
The cache system itself acquired an improve in late 2025, with repositories now capable of exceed the earlier 10 GB restrict by way of pay-as-you-go pricing. Each repo nonetheless will get 10 GB free, however heavy customers can now purchase extra moderately than consistently preventing eviction insurance policies.
What Groups Ought to Verify
Most workflows will not discover this restrict. However when you’re operating matrix builds that generate distinctive cache keys throughout dozens of parallel jobs, do the maths. A 50-job matrix finishing concurrently might theoretically hit 200 cache uploads in below a minute if every job creates a number of entries.
The repair is easy: consolidate cache keys the place doable, or stagger job completion when you’re genuinely bumping towards the ceiling. GitHub hasn’t introduced any monitoring dashboard for cache add charges, so groups involved about hitting limits might want to audit their workflow logs manually.
