Starting June 2, 2026, eligible container sessions will be billed per minute with a 5-minute minimum, instead of being billed at the full 20-minute session rate. The underlying per-minute rate will remain the same. This update is intended to make billing more granular for shorter sessions and will lower effective cost for customers.
