Reproduced this issue on edge. Airport symbols etc aren't loading at all on Firefox 127.0.2.

@james-rae @yileifeng any thoughts on this one? I assumed the airports were only drawing at the one scale level, but is there a problem with the service?

[james-rae]

I can follow up after the party. Will need to look through that huge XML service definition to see what scales are what. But I've also got some 403 results from geomet today so we might be hurting it's capacity.
