Hi, can anyone share best working HTTP health check examples with match string set?
We running into multiple outages caused by ATT U-verse/DSL WAN links as a secondary WAN or ISP.
In the event, if service is down for whatever reasons (non-pay, signal lost or others)
Majority of ATT modems wallgarden your connection and lend you to the page to resolve signal lost or make a payment. While this is highjack DNS and DNS health check shows that link as healthy and leave it on.
And depending on the WAN use scenario users ether complain that the Internet is slow, some site not connecting
all the way up to connectivity loss if Primary ISP has an outage while we didn’t realize that out ATT WAN link was down as well.
I’ve tried a few different settings and sites but my experience is very contradicting.
