The server timed out waiting for the request from the client.
HTTP 408 Request Timeout means the server waited too long for the client to complete sending the request. This is different from a server timeout (504) — here the server is ready but the client is too slow.
Frequent timeouts hurt SEO. Google may reduce crawl rate if your server frequently times out.
LemWatch tracks response times and alerts when they exceed your configured thresholds. This catches timeout issues before they affect users.
