There’s a couple of places I’d think to find information like
and apparently there’s a Reddit https://www.reddit.com/r/proweiqi/
Someone suggested Go News - Go to Everyone! for scheduled events.
Maybe something like https://www.nihonkiin.or.jp/event/ with google translate or deepl. There seems to be news/events sections.
The Jena go school JIGS, used to do news updates but I haven’t seen them in a while.
Aga does cover news from abroad, but probably mostly as summaries after it happened https://www.usgo.org/
