IP Address Changes

August 1, 2003 12:09 PM

In response to me complaining about the server this site was on being overloaded, my provider moved me to a new server. On the whole, this is a good thing. I'll notice a big difference, because it will no longer take fifteen seconds to rebuild an entry. Readers on the other hand, won't notice any change at all because the whole site is static pages anyway.

That is, if they can read it....

DNS is basically this big distributed cache, where the cache-entries get to determine how long they live. When changing the IP address of a host, you're supposed to progressively lower the TTL of that host's DNS entry before the change-date. That way, when the change occurs, the cached lifespan of the obselete entry will be really short, and not many people will be inconvenienced.

Unfortunately, I run my own DNS, and I wasn't told what the timetable for the IP address change was until after it happened.

So if you can't read this, it's because your DNS server still has the old address, and may very well hang on to it for a few more days.

Update: I had the TTL for my domain set to a week. Normal service may not resume for a while...
