crates.io slowness

Incident Report for The Rust Programming Language

Resolved

The primary source of the load appears to have been a scraper abusing our API. We have blocked the scraper and the replica database has returned to its normal heavily loaded state instead of being overloaded.

Identified

The read-only replica database used for many of our common queries is under heavy load. We are evaluating options to deal with this.

Investigating

crates.io responses are unusually slow due to database issues, with occasional 500s due to database timeouts. We are investigating.
