The reason we went with Viawest is that we're colo-ed in a very good facility (Level3's colo in downtown Denver) and Viawest is multi-homed through TouchAmerica, Level3, and Internap. Internap are themselves of course very well interconnected locally. Doing multihoming in-house wouldn't necessarily improve reliability; it'd just shift the failure point from Viawest's router to our own, meaning much more $$$ worth of router here and much more administrative load for me. I really doubt I can do a better job of running BGP than Internap, or even Viawest. -> leasing from ARIN is best for you. If you see continued growth, I would make -> the plunge and revel in the discoveries. Yup. Right now we've got a nice, steady, maintainable growth rate; unless our business model changes it'll be years before we need a /21. In reality a large and obvious "sea change" in the ISP business or in our business model would precede any need for a big block of addresses here. If things look like they're changing (or if it looks like Viawest and Level3 are both going under) I'll definitely be talking with ARIN; until then there should be no need. -> You can be allocated blocks from ARIN in a 2-3 week period of time; another -> provider bringing you a DS-3 (or whatever) could take 6+ depending on your -> location. One of the nice things about the Level3 colo (or any large colo, really) is that the slowest part of adding a DS-3 is the cross-connect. We got a DS-3 from XO a while back and XO's end was done in about 5 days. Took 3-4 weeks for Level3 to run the cross-connect, of course. -Robert Tarrall.- Unix System/Network Admin E.Central/Neighborhood Link
