An interesting use-case presented itself today. We had a DNS error for one of our sites that caused our domain to resolve to a parked IP. The fix was put in place immediately, and our desktop users never really experienced a problem, however, on most mobile networks, the issue persisted for almost 24 hours.
In our case, it would’ve been amazing to have synthetics checks which originated from mobile devices (on mobile carriers) which would have both alerted us to the error sooner, and allowed us to monitor the fallout more closely.
Not sure if this is something that’s ever come up before, but thought I’d bring it up, at the very least.
