--- title: Hookshot Load balancer author_name: technoweenie --- We had an issue with the Hookshot load balancer this morning, causing the majority of hooks to flow to a single node only. This lead to massive queue times. While fixing this, we're putting the old Services backend in use. This means the old IPs are back in use. Use this [Help guide](https://help.github.com/articles/what-ip-addresses-does-github-use-that-i-should-whitelist) if you already removed them from your firewall.
