Varnish allows you to have multiple VCL programs loaded, but only one
of them is active at any one time.
What you could do, is therefore to have VCL for maintenance, something
along the lines of;
sub vcl_recv {
error 503
}
sub vcl_error {
...
}
Load it with the cli commands "vcl.load maint <filename>"
When you want to go into maintenance mode, you switch to that VCL,
using "vcl.use maint"
when you want to get back to production, you switch back to your
normal VCL with "vcl.use boot"

Never attribute to malice what can adequately be explained by incompetence.
