I'm attempting to source dynamic data from the web (through R within sage cloud terminal, package httr). But every attempt, for any website returns in a "Failed to connect to url port 80: Connection refused", where URL could be really any web resource, e.g. an xml file accessible on the web

Is my session behind a firewall? Can I amend those settings then?

I edited this to remove a link that some people may have interpreted as spam. Please let us know how this is connected to Sage or you may be blocked in the future.

No worries, not banned! If you have a different example that isn't from a known ad source that would be great. Hopefully someone will have a good answer for you, especially if you are able to give a connection to Sage.

SageMathCloud projects at don't have network access by default. You can request network access for your project by emailing William Stein, giving your project id and declaring that you want this web access for good reasons (research etc.) and that you will not abuse resources (no spamming, no mining bitcoins etc.).
