Email alert if PC disconnects from ADSL

Thanks guys, for all your input. Yes, I'm using MultiCharts which I can only run on one PC at one time. I'm running API automated execution on forex, but need MC on my local machine for other discretionary trading (charting), so it looks like a backup ADSL router, plus email alert incase both go down is the solution. Longer term I will work towards multi licence / cloud VPS. Thanks again!

Have you actually thought about what you are asking? If your ADSL goes off where exactly is the email meant to be sent from? No ADSL means no internet, means no email. Also a backup ADSL may not be much use since the most common reasons for ADSL outage would be exchange/provider level which means it wouldnt really matter how many routers you have, in all probability none of them would work.

The proper way way to deal with this is as has been suggested a vps or hosted server solution. Its also a hell of a lot cheaper than any of the other solutions that would offer the same level of protection.

Something is going odd with this thread. Replies seem to be vanishing. Anyway. My reply might have been a bit cheeky but the point is still valid. You wont find an off the shelf solution that will allow you to monitor one adsl connection from another. Of course it can be done. You can ping router 1 from router 2, if it gets a reply chances are everything is OK. If it doesnt you can ping a known address (google maybe) to confirm that its not router 2 that is down. All this can easily be automated to enable an email to be sent if router 1 appears offline.

The caveats are that both routers would need to use different ISPs and be in different geographical locations (not on the same exchange). Either way vps will be a lot cheaper
