Claude.ai unavailable and elevated errors on the API • Hacker News Board

"We are investigating an issue preventing users from reaching Claude.ai, and will provide an update as soon as possible." Who is We? I thought software engineers were going to be redundant and AI could do it all itself? (not to take anything away from Claude code + Claude both of which I love)

I've never really understood this kind of sneer comment.

Someone should tell Anthropic that 89.999 is the wrong "four nines" of uptime

why does this even occur? if it's merely compute limitations, why not just 429 some requests?

Have you run a system in production? There are a multitude of reasons that a system can go down. There's no indication so far from Anthropic that this was merely compute limitations.

Yeah, this is not just inference. First thing for me was an MCP I use went down in Claude Code, models still worked. Now "API Error: 529 Authentication service is temporarily unavailable."

How are they going to fix it if the AI that designed it isn't working?

More than by the downtime I am much more surprised by the actual uptime. Hard to imagine how difficult this must be, given the speed of growth.

Truly! As someone who's worked with HPC and GPUs in a scientific research context, trying to get a service like this to work reliably is a different ballgame to your usual webapp stack...
