I have been on the 20x Max plan of Claude Code for a while now, however since last week something changed and I seem to have been getting lots and lots of those 529 errors.

My workflow hasn't changed, same level of concurrency as usual, did they change their limits?

That’s not what those error codes mean.

It’s the reason they’re giving for not providing what you asked for.

They’re not upset with you.

Why is your comment identical to another comment in this thread?

Whats the code for being upset? It isn't 429 either :)

I also started getting them around that time, and it seems unrelated to my usage, eg today I encountered it on the very first prompt of the day after a whole weekend afk.

Before you put your entire life in danger of being dependent on Anthropic products, please review my personal horror story and be very careful;

You won’t get any packets back from that server, but maybe some others.
