Was listening to radiosai on my mobile today with wifi for long periods while lying on bed, made the following interesting observations.
1. The changeover actually happened at around 6.32 as heard on the stream, but the shoutcast server went into the interruption music for more than ten minutes more, till the signature tune finally came, around 6.44. Meaning the stream is buffered by 14 minutes due to the two servers?
2. By afternoon, the delay was around 7 minutes - The dd which was supposed to get over at 2.41 was heard to end at 2.48. So somehow the buffering delay was reduced ?!
