I am having an on-going problem with our 64KBPS Shoutcast stream. It plays the first song properly after someone tunes in but starting on the next song the playback "stutters". Sometimes during the platback it will correct itself after 30 seconds or so, but usually once the problem starts it does not correct.

I had this problem a couple of weeks ago and SA support said to run a tracert. I did and found that a particular server was always "trapping" the feed.

I actually called the company that owns the server and they corrected the problem for a day or two. Now, the last two days I am stuck with the same problem. And, once again support says my hop times are too long. Here is the most recent tracert which is typical of all I have done:

I am at wits end to correct this problem and it is severly affecting our listenership. Any suggestions will be appreciated.

From what I see in your traceroute you got some severe problems with your provider.
While the first two hops behind your router are ok the 4th hop is way too slow for being inside your provider's network and thus probably in the same geographical area. (You shouldn't have any ping greater 100ms if your data stays inside the U.S., I even get a response from that spacial server in shortly over 100ms and I'm living in Europe)

The bottleneck of your connection is definitely host977300265.direcpc.com.
All the packets to the hops behind that need to go through that gateway first and each packet that arrives at it's destination is only slightly slower than a packet that only needed to travel to that particular host.
I'm assuming dircpc.com is your ISP (or at least the domain belongs to your ISP's company) since all the first few hops behind your home-router belong to that domain.

Thanks for your quick reply. Actually we are on an industrial strength HughesNet enterprise server which is usually as fast as greased lightening. I have documented this enough now via tracert that I am going to get in touch with our Enterprise support team and kick some butt. I'll keep you posted. We are in the process of installing a T-1 line as a backup.

Hmm yeah I just guessed on the home router part since there is one local hop before the rest of the traffic goes into the public interwebs.
That's kinda uncommon in hosted servers, but still the bottleneck is with that direcpc company. (Sorry, I don't know that much ISPs in the US and even less Hosting providers)

The situation is that HughesNet has sold more bandwidth on there satellite than they have available. We went through this once before but then we migrated their top of the line satellite and transmitter and all has been well for the past 18 months.

So I notified them today that we have started construction of the T-1 amplifiers and repeaters so the problem will be gone in about 20 days. Thanks for your input. We are just going to cut the ShoutCast stream until the changeover: we still broadcast on 2 other streams and this doesn't affect our primary one. It's just a pain.

I don't normally recommend HughesNet for any level of streaming. The travel time for packets is just too high a latency issue for the SHOUTcast and most other streaming servers. I do understand that for some HughesNet is the only option but if you have another option I highly recommend not using a Satellite provider.
