The IAR was the source of my notice as well and is what started me down this path of cat herding. I would think that it would only be polite to notify people about what is going on so that other people do not waste their time looking for phantom issues. - Michienne Dixon Network Administrator liNKCity 312 Armour Rd.

If they are going to involve our AS numbers and trigger alarms it would be nice to notify us first... especially on something as major as a prefix hijacking (potentially) Paul
