Pros/Cons Dual Best Effort ISP vs Fiber/MPLS.

@Dashrender Well you can make another wild {censored} guess like the rest of us do, lol.
But Here, I think is where the rubber meets the road. If what you are doing has the ability to improve internet speeds and (both cut cost and improve reliability [through use of a backup connection]) , how is that a bad business decision?

Great - how do you quantify the actual risk?
All I know right now is I pay $880 and in 7+ years I've had 15 mins of unplanned downtime.
I pay $120 at another location and I 3 different days at 4 hours per day of downtime.Risk is difficult to assess, especially in a case where you have to consider more than technology. The biggests risks that you have to address here are around scope (you are dealing only with service risk, but what if your building burns down or your own equipment fails!!), risk around businesses going under or changing policies, risk that you will be considered a pain to fix and traditional downtime could suddenly become insane downtime, lock in risk, risk because of service quality issues, potential downtime, likely downtime.... it's hard, very hard. That's why risk analysis is one of the absolute top skills for IT decision makers. It is complex and often the most important value that we provide to the business - without risk analysis they could just pick a solution themselves without IT being needed.
Risk is a bit of a soft science, but understanding the range of risks, a rough idea of likelihood, what risks apply how heavily to the business in question, how well mitigation factors can or should work, etc. is what IT provides and while far from perfect, it can be pretty decent.
And it is important to remember that we are only coming up with risk. And this is multidimensional risk not just a 20% kind of number.

I won't post publicly dollar values of lost revenue.. not that I know what it is anyhow, the power that be won't share with me.
Ok, that answers part of it... you have no way to calculate the financial risk of downtime if those people won't work with you.
Just some basic math on the links alone (hopefully I did them correctly) The first one costs you ~$1.21/hour. Meaning you lost ~$0.30 on those 15 minutes of downtime. The second one costs you ~$0.16/hour. You've lost $1.92 for all those 12 hours you were down. In total though you've spent $73,920 on link 1 and $10,080 on link 2. Just something I thought was interesting.

I pay $120 at another location and I 3 different days at 4 hours per day of downtime.That's all very misleading data, sadly. Because a new connection will not necessarily have anything to do with what you have seen elsewhere. Might be the same, might be better, might be worse. And sadly, seven years of a fiber line is not enough to get insight into the failure rates because outages tend to be very long and very infrequent. Like a volcano.
Take this scenario..... if you were to have lived in San Francisco for three generations you would report that while there are tremors and little earthquakes, there is nothing scary ever. A little concerning maybe, but not scary of dangerous. Yet if you take a long view, scientists know that an earthquake levels the city and kills a huge number of people every 110 years or so. It's very regular and very dangerous. But 90 years of observation would make it seem like this wasn't a real risk.
When dealing with infrequent risks, observation is a dangerous thing.

I really don't think most business need dual links. These days a good ISP rarely goes down when it's not planned. The only reason we had it at the town was because of the police department there are things they need in an emergency, information on past crimes as well as facebook (which they can only get their special access to inside the network) Facebook is become more valuable that most people realize in detective work and active shooter situations.

I was thinking this as well. If there was a good wireless provider in the area get a 4G/3G modem in the mix as failover and you eliminate most ISP related downtime. I rarely hear of cell towers going "down".

They do, but one of the great things is they tend to go down from completely different events than land lines tend to go down from.

I would agree with that, that most do not. Same factors that make most appropriate for consumer or prosumer links.

A lot of cell towers around here aren't running generator backups so they go down often.
-
The thing about a cell tower outage is that nearly all people just see it as a "gap in coverage." It's not like losing a terrestrial line, it appears very differently to the end users.

But not to a non-mobile secondary link. In that case it would be considered down. Although as you said, generally ISPs and cell service don't go down at the same time.

Ouch, that could be an issue for sure.

Still depends, coverage varies all the time and an outage of a tower might only look like a drop in quality.

I just had an interesting conversation at lunch.
So far, pretty much everyone here (as far as I can tell) have considered my idea of dumping the expensive fiber line and getting two commodity ISP links as a general good move. Of course a few of you have said something to the effect - prove to me that not being down is worth the extra costs - and I'm understanding that.
So, in my lunch conversation, and PSX will love this, my associates told me I was looking at it all wrong (granted you all have to, just for different reasons). To them the fact that I am even considering getting rid of the fiber connection is unthinkable. Why in god's name would I get rid of a pipe that has proven itself (yes I read your post Scott) so reliable. Instead of getting rid of that, if down time is really an issue, or as it appears, additional bandwidth is needed/desired, but the cheap best effort connection in addition to your current fiber connection, route your EHR and SIP traffic through that (with failover to the best effort) and push everything else off to the other pipe.
So instead of saving my company nearly $600/month, raise my price by $200.
Thoughts?

If that's what the uppers want I'd just do it assuming you presented the case well.

Basically it's a conversation in a bubble. Like everything else, his recommendation is worthless without the financial data. Is spending $200 worth it for the additional speed? I can't answer that.
The thing that you proposed was lower risk, higher speed, lower cost. Win / Win / Win regardless of other financial details. It was a "guaranteed" improvement. Maybe not the best decision, but a known move in the right direction regardless of what factors matter to the business.
What this guy is proposing is faster and more reliable but much more costly. So Win / Win / Loss.
Which is better, a pure win? Or a tradeoff where you don't know which factors are the ones that matter? If only cost really matters, you might be screwing the company. If intense reliability doesn't matter, you'd be screwing the company.
So honestly, I think he's being reckless and illogical - just throwing away money because he's using emotion, not logic, to deal with the ambiguity of not having the details necessary for you to do your decision making.

It was an associate. I doubt it was an upper.

Lunch was with friends, not management - I see their (my friend's) point, and if management signs off GREAT! but since I already made the mistake of talking to my boss after the possibility of lower costs... this will be an unpleasant conversation to say the least.
-
Most of us (I think) see the lower cost + faster internet + the added benefit of failover / redundancy for your ISP as a win though...

Details only for the sake of conversation were as follows,
Company looses $1000/hr of downtime (all other loses are actually deferred income, because they would be rescheduled).
Company grosses 12 million a year, employees 80 people. The save of $8600/year moving to pure commodity is but a blip on that radar, and 'to them' isn't worth the potential risk by moving to a pure commodity setup.
