The change is Saturday Evening. Because almost all of our domains use SHAVEN as the secondary, there should be no problem with this change. Changes should trickle down within an hour of the move (unless some ISP caches records longer than we specify).

If the YAK does not do your DNS, you'll have to change your own records. Let X=404.

We don't know the future addresses yet. Let Y=452.

Most domains related to the YAK list TERTIARY.YAK.NET and SHAVEN.YAK.NET as their DNS servers. Only the address of TERTIARY will change, so DNS should be stable during the move due to SHAVEN; updating the NIC does not have to be done immediately. Let Z=5484.

The A records for web sites and email, however, will have to change in synchrony with the move. So check this page frequenly, or be in contact with strick, whose cellphone number is X-Y-Z. Leave remarks at the bottom, or try email.

Suggestions

• DNS: Hopefully SHAVEN.YAK.NET (216.218.244.7) is your secondary. It's not changing. That'll make your DNS work during the move. If TERTIARY is your primary, we'll change the address of TERTIARY at the NIC, and I think your domains will catch the change.
• EMAIL: If yak.net does your email, your MX record should point to YAK.NET. We'll fix that rapidly when we move.
• WEB: Make your www.whatever.blah record a CNAME to SHARED.YAK.NET if its address is 209.125.90.77. We'll fix the SHARED.YAK.NET name rapidly. Unfortunately, you probably can't use CNAME for the name without www (just whatever.blah). So you'll just have to check every hour or so, and when it breaks, change it. Watch this page for estimates on when we move.
• TTL: Make your DNS Time-To-Live small, like 2000 seconds. Do it now, in preparation for the move.
