DuckDB extension backup server

This domain is an independent backup for DuckDB extension distribution, operated by the DuckDB Foundation. It mirrors the official repositories and is kept current automatically. Use it if extensions.duckdb.org or community-extensions.duckdb.org is unreachable.

Core extensions

SET custom_extension_repository = 'http://extensions.duckdb-backup.org';
INSTALL httpfs;

Community extensions

INSTALL h3 FROM 'http://community-extensions.duckdb-backup.org';

Both hosts also serve HTTPS. Extension binaries are identical to the originals, so signature verification works unchanged. Add FORCE after INSTALL to overwrite an existing installation.
