On the other hand, `notify.trafficmanager.net.`, the domain name used for Edge push notifications through Azure Traffic Manager, currently points to `notify1.ontario.ca.` with a CNAME record. This resulted in an Edge push notification outage a couple weeks ago, but they never fully fixed it. Push notifications are working again because they use subdomains of `notify.trafficmanager.net`, but `notify.trafficmanager.net` itself is simultaneously used by one of their Azure customers--and they seemingly have no idea.

In other words: `*.notify.trafficmanager.net` is special-cased, and this has caused problems.
