Just wondered what link monitoring people use on their GTM's. Basically I would like to ensure if there is any problem upstream of our ISP router that the data centre associated with this link is marked down by the GTM.
Many Thanks

Common options are to transparently monitor one or more external web sites that should hopefully not go down, like bbc.co.uk. You should be able to configure multiple checks and then mark the link up if any of them succeed.
