Watching my Unbound DNS cache statistics and sadly there’s plenty of Fediverse servers with TTL of A/AAAA records set to very low values. Why would anyone set TTL to 18, 30 or 300 seconds?

I get it, when you prepare for a migration, that’s something you want to do to speed up the transition. There’s some sophisticated load-balancing schemes where this may come handy, but most of those I see are simple unicast hosts. Resolvers worldwide are just pointlessly pounding the whole DNS tree to get the same IP over and over again…

RFC 1033, 1987:

Most host information does not change much over long time periods. A good way to set up your TTLs would be to set them at a high value, and then lower the value if you know a change will be coming soon. You might set most TTLs to anywhere between a day (86400) and a week (604800). Then, if you know some data will be changing in the near future, set the TTL for that RR down to a lower value (an hour to a day) until the change takes place, and then put it back up to its previous value.

Okay, this is about default TTL in SOA and 86400 may be quite long for disaster recovery, but how about at least an hour (3600)?

Hey, when I'm feeling depressed, I just stop having sad thoughts (and reduce the part of brain network responsible for this), why can't you? 😬

The foster kittens are getting a health check today and will probably "graduate" into being spayed/neutered and put up for adoption.

We started with 7, lost 2 to parvo, were told the other 5 had little chance.

All 5 are now happy healthy and bouncing off the walls!

I will miss the hell out of the little buggers but I think they have been given a good start and will make their adopters very very happy!

My #programming traumas over the years make this dish quite difficult to eat, let alone digest.

What is the font they're using?

And what is the code page?

Do these noodles have proper #unicode support, or will we be stuck with some bespoke and more-broken-than-normal #emoji implementation? (so far they only seem to support monochrome chicken)

Did they switch to € noodles because their $ noodles allowed environment extraction attacks?

Questions upon questions...
