This Twilio Segment API SLA will not apply to any Segment Services, or versions thereof, that are (i) no longer available or supported or (ii) identified as alpha, beta, not generally available, limited release, developer preview, or any similar Segment Services offered by Twilio.

Target Availability Scheduled Maintenance will not exceed five (5) hours per month in the aggregate and, to the extent practicable, will be scheduled during the weekend hours between 18:00 Friday and 3:00 Monday Pacific Time.
