If you can read this (and in some parts of the 'net, you probably can't), then you're reading it through our new network connection via Comcast. After a pretty nasty false start over the weekend, and the cutoff date for Dataflo coming up this weekend, I bit the bullet and cut things over this morning. DNS was set up such that NS records were available for both address assignments for a while now, as well as MX records pointing at both address pools, so the only thing that's really off the air right now in some places is the webserver, and that'll just have to wait. I also managed to break my backup MX along the way, so I'll need to poke at that a bit more and see what I fat-fingered.
Bah. I like renumbering about as much as I like moving.
So, some initial observations: latency is a touch higher than it was with Dataflo, surprisingly enough. First hop averages went from 2-3 ms on the old wireless link to 8-10 ms (with occasional spikes) on Comcast. On the other hand, I'm now seeing download rates around 6Mbps (vs. 1.5Mbps), which is a nice change of pace. Downstream speed is 768kbps now (vs. 1.5Mbps through Dataflo), which may prove to be a problem, but we'll see how it goes for now.
The biggest negative observation I've made so far is Comcast's complete lack of business-oriented customer service; they're obviously incredibly used to dealing with residential customers, and they've used that same contracted-out infrastructure to deal with their commercial customers as well. Phone support is excellent (when you finally get to them; getting a rep on the phone requires navigating about 10 levels of phone menus), but getting physical on-site service is a multi-day waiting game, with the typical "we'll be there sometime between 8:00 AM and 8:00 PM" kind of scheduling that you've come to expect from their residential service. There is no email interface to the helpdesk whatsoever; any kind of technical support inquiry MUST be made by phone, which is incredibly annoying when wanting to do something complicated with DNS. So far, I'm not impressed, but if I never have to deal with their customer service (much like when I was with Speakeasy, who rarely saw an unannounced service outage), then it won't matter to me. We'll see.
