Concurrent Site Startup Limit

Description

For sites on Small Worker instances, we limit restrict the number of sites which may concurrently start to eight (8). We do this to ensure that machines are not overwhelmed when too many sites start at the same time.

The limit is not configurable.

Notes

If more than 8 sites are requested to start simultaneously, the site starts are queued. As soon as one site start completes, queued sites will be automatically started.

Requests for sites which are queued are still subject to a 4 minute timeout. If the request expires before the site could be started, the client will receive a 502 response.
