How often does the production IP address of Canvas change? For instance, yesterday miamioh.instructure.com was reporting 3 IP addresses and today it's reporting 2. The reason I ask, I work at a help desk and someone was having issues accessing Canvas. eLocal.com was being returned instead of the Canvas site. It appeared their HughesNet equipment was overriding DNS lookups and using cached info and the IP has now been assigned to a different AWS customer. Today, another user had intermittent problems but the site worked fine after they called in. It sounded like they were using public/hotel WiFi and they were using an old IP. The site quit loading for them but started working again by the time they called.
