Ugh. I finally bit the bullet, and had Comcast "Workplace" service installed to replace the flakey fixed-point wireless service I've been fighting with for the past two years. To be fair, I should qualify that: my "last mile" link (between my rooftop transmitter and the tower) has been rock solid. The problem has always been mid-day routing and configuration changes on the part of the provider, which have knocked me offline anywhere from a few minutes now and then, to one incident that had me offline for the better part of a day. At this price and service level, that's completely unacceptable. So, since I can't get service from my preferred vendor here due to a complete lack of DSL availability in my area, I'm stuck with the local cable company: Comcast.
So, first impressions (note that I haven't moved ANY services to this yet, until I get a feel for how this will work): 6Mbps download speeds are unbelievably fun. The 768kbps upload speed may end up being a bit of a hindrance; most of my traffic is SMTP, but I do receive a fair bit of HTTP traffic too, and that's where that upload bottleneck is going to suck (specifically, both I and Erica maintain pretty large photo galleries that seem to get a bit of traffic, and I'll often host larger items for people for limited times). But, we'll have no idea how that'll go until I bite the bullet and cut stuff over; I'm hoping I can run fairly well off of both links for a while, with plenty of time for DNS updates to propagate.
Ugh. I remember how much I hate renumbering now.
