Pfsense doesn't detect offline WAN connection?

[coolVariable]

Pfsense is set up to load balance between DSL and Cable WAN.
We switched phone providers on Friday which disabled our DSL.
Strangely enough, on Monday pfsense still happily reports the DSL to be "online" though it obviously does not work anymore.
WTF?

Change the ip address or the route to reach this ip you configured to monitor this link.

That's what happens if you're not actually monitoring your connection status, but using your modem's IP or similar as your monitor IP. Use something on the Internet for that.
