I don’t know if this impacts anyone else, but I just tried opening this website on Microsoft Edge, both on my work laptop on the work network, and a personal laptop which is not on the work network. Both times Microsoft Edge blocked me from accessing the website, suggesting it was a Phishing website. I reported that I don’t think it is phishing, but, it may be better coming from a site owner if this affects other people too.
Thanks for the heads up, curiously I don’t get this at the moment, don’t know if it has been resolved by Discourse in the since you posted, or whether this is a feature that’s not turned on in my browser though?
I think this applies to the discourse.group domain in general rather than the Cylc subdomain in particular so we’ll need to poke Discourse.
