http://docs.atlassian.com/ is currently unavailable from the UK, so I can’t access https://docs.atlassian.com/jira/REST/latest/jira-rest-plugin.wadl in order to build my Cloud add-on
Our apologies, service should be restored shortly. See my post here: Service Outage and Restoration: docs.atlassian.com
I’d also like to take the time to apologise @jbevan for the connect.atlassian.com and now docs.atlassian.com issues you’ve run into. We’ve only had two incidents in the past 6 months with our documentation and you’ve managed to run into both of them. Lucky you! We’ll try and ensure that the rest of your Atlassian development experience is more reliable.
