What domains do I need to allow to access Scratch?

Modified on Mon, 12 May at 9:03 AM

In order for Scratch to be accessible, the following servers need to be whitelisted (i.e., not blocked) by your network:

If you can use wildcard domains:

*.scratch.mit.edu

*.recaptcha.net

*.gstatic.com

*.wistia.com

*.wistia.net

*.akamaihd.net

If you can't use wildcard domains, this is the current list of every subdomain. However, we add new services under subdomains frequently, so this list could get out of date over time:

scratch.mit.edu

api.scratch.mit.edu

projects.scratch.mit.edu

cdn.assets.scratch.mit.edu

cdn.scratch.mit.edu

cdn2.scratch.mit.edu

assets.scratch.mit.edu

clouddata.scratch.mit.edu

download.scratch.mit.edu

downloads.scratch.mit.edu

uploads.scratch.mit.edu

www.gstatic.com

fonts.gstatic.com

www.recaptcha.net

wistia.com

fast.wistia.net

embedwistia-a.akamaihd.net
