Additions and changes to the Twilio platform
Twilio sells Call per second (CPS) which allows customers to increase the rate at which Twilio will execute new calls created via the Calls API. CPS is sold and billed in us1 and the CPS value is replicated to other Regions (e.g. au1/ie1) at no additional cost to allow customers to operate across all timezones. The replication of the CPS value also allows services to fallback to a different Region in the event that a Region becomes unavailable. Twilio has updated the Acceptable Use Policy regarding concurrent utilization of CPS across Regions; specifically persistent maximum utilization of CPS in multiple Regions concurrently is prohibited. For more information, see the Programmable Voice: No Concurrent Voice Calls per Second in Multiple Home Regions section of the AUP.
