Packagist Update Schedule

How often does Packagist crawl newly added packages?

New packages will be crawled every five minutes.

How often does Packagist crawl existing packages?

Existing packages will be crawled every hour.

How often does the Packagist search index update?

The search index is rebuilt every hour. It will index (or reindex) any package that has been crawled since the last time the search indexer ran.

Can Packagist be triggered to recrawl a package (on commit or by other means)?

Not yet. :) Want to help? See #81 and #67
