A polymeric material comprised of at least one random copolymer comprised of ethylene oxide and one or more other alkylene oxide and at least one non-random polymer comprised of one or more polys has been discovered. A pulse electrothermal ice detachment apparatus includes one or more coolant tubes, and optionally, fins in thermal contact with the coolant tubes. If the destination number has not been ported, the signal transfer point sends a return message to the originating service switching point indicating that no changes are to be made to the IAM. In addition, the circuitry also receives optical signals from the optical cable and outputs corresponding electrical signals to the electrical plug. The failover module may be configured to facilitate launching a new virtual instance in a recovered state that reflects a last known operational state of the failed virtual instance. The devices and methods for brewing and steeping tea utilize steam, heated liquid, agitation, and recirculation.
