Slashdot Mirror
Slashdot is Moving
As I mentioned yesterday, Slashdot is moving from Exodus East to West. This will be happening at around 11pm Eastern. We hope the downtime will be relatively minimal, but DNS may be a little slower to catch up. You can use brak.slashdot.org for a few days if your DNS is slow to catch up to reality. Hopefully we'll see you on the other side. Hopefully. In the meantime talk amongst yourselves. Here's a topic: Is Agent-X Deadpool?
Set the expire times to 12 hours a few days in advance, 4 hours on the last day, then half an hour in the last 5 or so hours, and three to five minutes for the last forty minutes?
Why bother? With tinydns, you can specify a timestamp for each record and automatically handle updates:
You may include a timestamp on each line. If ttl is nonzero (or omitted), the timestamp is a starting time for the information in the line; the line will be ignored before that time. If ttl is zero, the timestamp is an ending time (``time to die'') for the information in the line; tinydns dynamically adjusts ttl so that the line's DNS records are not cached for more than a few seconds past the ending time. A timestamp is an external TAI64 timestamp, printed as 16 lowercase hexadecimal characters. For example, the lines
+www.heaven.af.mil:1.2.3.4:0:4000000038af1379
+www.heaven.af.mil:1.2.3.7::4000000038af1379
specify that www.heaven.af.mil will have address 1.2.3.4 until time 4000000038af1379 (2000-02-19 22:04:31 UTC) and will then switch to IP address 1.2.3.7.
