The internet connection dropping isn't much of an issue, miners will reconnect to the pool right after the internet is back up.
I can confirm this. Miners will keep trying to reach the pool as long as the mining software is still open. My internet cuts out occasionally, but the miner will keep trying to reconnect until the internet comes back.
This is obvious.
My question is if the Internet connection drops for 3 minutes, would this be causing only 3 minutes of lost mining time, or could it be potentially causing say 20 - 30 minutes of lost mining time, due to the miner requiring being connected for the full duration of its "session" which say takes 20 - 30 mins per sesion.
Let me put it this way. If you need to carry a large bowl of water from point A to point B, and then somewhere in the middle on the road you accidentally drop the bowl , it breaks down and spills the water, you can't just continue on your way. You need to get back to point A get another bowl of water and mange to carry it intact ( i.e without the Internet connection dropping ) for the full duration of the course.
So the Internet Connection may drop/cut for only 1-2 mins at a time... but if the miner has to restart from the beginning of the job, you are actually losing much more in mining-time, each time your connection drops.
