Bill Simpson does not have his facts on the fiber cut to the old NSFNET NOC in Ann Arbor quite right. There was a cut and the NOC was cut off which wasn't good, but it was not the case that separate links were purchased to avoid that completely. We knew that there was some risk depending on where cuts took place. As I remmeber this happened twice in the 7+ years of the NSFNET agreement (two times to Michigan). -Jeff Ogden Merit
