If it is happening with Celt Rock Radio then this is a Live365 issue. They might be getting alot more listeners today becaue of the St. Patrick's Day issue.
Thats good to hear Highlander Radio is clearing up. We reduced some bandwidth on that channel. This is some good feedback as we are going to make a few changes after today to help things like this.
We definitely hit an all time listener High today and with 512 members logged into our site at one time! Bit of growing pains, we will have until next year to increase our capacity again!
