Or another site whose monitoring system monitors the primary monitoring system. Chances are one of them can reach the Internet and your mobile provider's SMS gateway, and tell you you've been partitioned, if nothing more specific. I've done this even at (pairs of) very small sites, in preference to bothering again with IXO/TAP and a modem. It's cheaper than a POTS line, if the second site exists already for some other reason (such as backups). The modem thing injects it pretty quickly, and it used to go over the air quite soon after that. But with everyone using data, sometimes to excess, I would anticipate potentially long delays in SMS even after it leaves your hands. A list of people, on different carriers, is good diversity, too. _______________________________________________ Discuss mailing list [email protected] http://lists.lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
