If you or someone you know has an account on mastodon.cloud, I would highly recommend migrating to a new server. Lots of instances are in the process of completely blocking mastodon.cloud which will sever all connections for people on
mastodon.cloud. Mastodon.cloud is effectively abandoned, running very old and out of date software with minimal moderation resulting in a good deal of moderation work for those of us running other instances.
I am posting this in hopes that some people on mastodon.cloud see it and decide to take action.

It's a victorian tradition at easter to sit down with a coffee and hot cross bun and stare at the Bells beach 'on-hold, call at X' count down timer.

Every school year, at exam time, many countries turn off internet access to stop cheating. Someone far more suspicious than me might suggest it is practice for more nefarious purposes.

Celebrating a success at WSIS+20 An important milestone in the future of the global internet arrived this week. At the United Nations General Assembly in New York, countries came to consensus outcomes in the twenty year review of the World Summit on the Information Society (the WSIS+20 review).

Also there might be less spurious arguments about governance, allowing airtime for other important arguments about AI and global junkets. also yay!

This is specifically to shift more residential usage to the daytime. Peak residential usage is still early evening when solar generation has stopped in the north or is low in the south. More batteries and VPP might help but behaviour changes are the most effective.

I've heard from a lot of my ex-colleagues at #AWS in the last few days. Seems like the layoffs were brutal in #australia
Some who were not laid off are also leaving. The stress of waiting for the next round, which will come just after performance review time, is too much.

ok, so the mismatch rates have not entirely returned to previous levels. Without talking to the Swedish registry (IIS), I'm not going to know why. If I become rich, I'll retain lookup data to analyse this myself in the future.

Golden retriever takes baby koala for a joy ride When Steve Lamplough heard a commotion outside his south-west Victorian home, the last thing he expected to see was a joey koala riding his dog like a racehorse.

This isn’t as surprising as it might seem. Many marsupials have the instinct to climb on something fluffy and they can do it fast. Even when very young.
Luckily I only need to worry about ring tails and brushies climbing onto my dog

with Today's stats updated, its appears the spike was transient and probably the result of a large roll over. .ONLINE on the other hand has been trending higher mismatch rates for a while and has also jumped.

Daily CDS Usage Charts Charts showing CDS usage on the Internet. Updated daily.

If you're associated with .SE or .NU, is there an explanation why mismatch rates for CDS records suddenly jumped in those zones?

could be just a timing thing with a large operator rolling keys at the same time. I'm curious.

I've updated CDS tracking charts to show 360 days of aggregated trends. TBH the trend is pretty clear. CDS usage overall is going down and TLD zones are less correct over time. possibly related
