Firewall / whitelisting


Hi there,

Could you tell me if there are any urls we need to whitelist to make sure has zero issues with our school district’s content filter / firewall?

Thank you,


Hey Darrell,

Great question. Currently, these are the sites you may need to whitelist. Please note, these are subject to change as we update our site: (this step may not be necessary, but squarespace houses and it at least needs to not be blocked.)

Also websockets need not to be blocked. Users can test here:


Thank you, david.

Much appreciated. Might be useful to pin this and update the sites as needed as you change and grow.
