Scheduled Maintenance
From Thursday, November 21, 22:00 - 23:59 PST, one of Twilio's carrier partner in US will be conducting maintenance to improve the service on their voice network. Maintenance will only affect a subset of Twilio's North America Toll Free phone numbers. During this maintenance, the carrier does not expect any impact, because they will be doing the maintenance on only one of their clusters, so the calls will be handled on the other cluster.
