After a server migration, builds against a self-hosted package registry got two minutes slower and every report pointed at the move. Every failing request was a 500 in 45 milliseconds; the entire regression was npm's retry backoff. The root cause was one row out of 63,000 still pointing at an object store that no longer existed, and the check written to catch exactly that iterated a hand-written list of tables and missed it.

Anthropic shipped Opus 5.5 today at $4/$20 per million tokens, and its own table puts it ahead of Fable 5.1 and GPT-6 Astra on agentic coding. The independent numbers are smaller, the code-quality numbers are mixed, and thinking can no longer be turned off. Sonnet 5.5 is not out yet.

S3 has no empty directories, and in a fully packed git repository the refs directories are exactly that: empty. A file-by-file sync carried every object intact and dropped the two directories git requires to call something a repository, so 84 of 517 came back unreadable while the database still said they had commits. The migration's health checks stayed green the whole time, because none of them ever open a repository.
