The pre-receive hooks README lists network as a resource hook scripts may use, but doesn't mention that GitHub Enterprise Server now restricts it. GHES 3.18+ logs hook network calls and lets administrators block them; GHES 3.22+ blocks them by default.
Changes
pre-receive-hooks/README.md: added a short paragraph in the "Performance, stability and workflow implications" section — immediately after the discussion of resources contended by parallel hook runs — covering:core.pre-receive-hook-networking-enabled.Documentation only — the example hook scripts don't make network calls, so no script changes were needed.
