I will be performing an update on the systems used for stopping/starting streams today. All shoutcast streams will need restarting, but this will only cause a few seconds of downtime and then the servers will come back up automatically.
This is intended to resolve any issues with servers randomly stopping as reported by a small number of customers.
The restarts will be performed over the next few hours.
UPDATE: This is now complete on all servers apart from USA3-VN which needs some more work before the change can be made. Updates will be posted here on any maintenance. This will be within the next week.
