Getting consistent "API Error: 500 Internal server error" messages in Claude Code right now (10:20 AM EST)

Their completion endpoint[*] is returning 503 with a `fault filter abort` response

[*] https://claude.ai/api/organizations/<ORG_ID>/chat_conversations/<CONV_ID>/completion

for me it's

API Error: 529 Overloaded. This is a server-side issue, usually temporary — try again in a moment. If it persists, check https://status.claude.com.

529 and not 429?

429 is if you have been rate limited. 529 is for server overloaded and can't process more.
