Me - Work from home. bring my servers/websites from the colo faciility saving $500/month.
If your servers (at the p4rice) are generating enough income to cover that, pay your salary, fill the supply chain with product, and pay your employees, then you just need a T1, a concrete bunker, redundant power (for off times) and a backup from Hell.
Otherwise, you're paying too much for your hosting and Fiber won't make a difference in that.
I do like the work at home... but if you can connect your site at the same speed as your users, you're i n the game from the get go.
And if your traffic/bandwidth is that dollar amount, then you certainly don't want to put all your eggs on one basket (your house). Been there, done that, lived to regret it. :)
The "What would you do with" question is about YOU, not your site... as that run along a different network than consumer linkage (or should!).
