We are currently experiencing an interruption of Internet service for our Spaceway customers. Our network engineers are working to restore service as quickly as possible. We don't anticipate service to be restored until sometime in the early afternoon on Wednesday the 5th. We apologize for any inconvenience this may cause you. Additional updates will follow.
