I actually began the process of migrating my domains (willfe.com, willfe.net, and willfe.org) over to a different registrar that supports dynamic IP addresses in their DNS service last week, but because of a screwup at the current registrar (sigh … so nice of their “protected domain services” to “forget” to forward mail to me…) I had to cancel that transfer and start it again, but this time the confirmation mails actually arrived and so the move is officially in progress.
I’m told that the registrar switch doesn’t actually kill anything in DNS but I don’t completely trust this; it is entirely possible that the site, or mail to it, or the domain itself might temporarily vanish if something goes wonky. Because we live in a world occupied by humans, something is likely to go wonky 
Consider that fair warning that there might be an outage over the next couple of days.
