I've been secretly hoping no one would notice Covad's ascension to the number one spot (which we've held for well over a month now ;). I actually made it through the last NANOG without a single mention of Covad's route bloat! There are no mistakes or excuses here. And there's definitely no renumbering going on. We were actually fully aggregated until an unfortunate incident this past May involving a distant service provider leaking our specifics. Gigs of traffic somehow vanished into Eastern Europe. The net result was deaggregation. It's unlikely we will aggregate down to less than 10 netblocks again. However, we do make every effort to aggregate where possible. Our superblocks are also being advertised, for those of you that want to filter our routes. Want to discuss further? Great. Call me or email me directly. Contact info is below. Think you can do it better? Even better. It turns out I'm hiring. :) Regards, Brad -- Covad Communications 408-434-2048 broldan(a)covad.com
