Delay in 1033 error page showing after Argo disconnect

Hey Cloudflare,

Argo is working absolutely brilliantly and so is everything else on Cloudflare for that matter.

The issue I am having is after Argo disconnects (e.g. service stops), there is about a seven minute window where a plain text “503 Service Unavailable” message is shown.

After that time, the custom 1000 level error page is shown.

Can that seven minute window be brought down to a few seconds?
