SPKmes, it appears you have found backbone hell. The data is nice, but isn't full.
Download Ping Plotter(free for 30 days) and run it. If you save it to a log, either post the log or send it to me. Ping 206.16.60.38 and something like pingplotter.com or altavista.com, so we can see the comparison. Here in New Hampshire, USA, the attens.net seems to overload very often. I've been working on trying to find a proxy workaround, but that adds difficulties of it's own.
