i keep passing my bandwidth mark every month and am paying around $10-25 dollars in overage fees. Business internet doesn't have a limit. Has anyone tried upgrading their service from residential to business? what sort of questions do they ask or do they just give you the service?
I use Comcast business class, and love it. Not only the lack of bandwidth limits, but the fact that you get to call a different number with no discernible hold times if you need help, and they will have someone out to your location within 4 hours no matter what time of day it is. I got home late one night and called at 2am, and they asked if I wanted someone to come out now or first thing in the morning. I told them now, because I "needed it for work in the morning", and the guy was calling me to tell me it was fixed at 5am.
They don't make you prove that you have a business, and if they ask I just say I need it to work from home or some shit. The two things that are different are that you have to sign a contract, usually two years, but if you were to move somewhere that didn't have Comcast they'd terminate it with no fees. You're stuck with it for two years otherwise though, except the first 30 days or so I believe (but check to be sure) when you can change your mind. Also, you HAVE to rent their business gateway, you can't get your own modem. The reason they gave was for speed of troubleshooting, but whatever the reason, you're required to have it.
Your mileage may vary of course due to being Canadian with a different company, but that's my experience with Comcast. Given that it is Comcast, I have nothing but good things to say about it, and after I dropped the TV portion of the bill I am still saving over $100 a month, so it was worth it. Oh, and I use a VPN for all of my pirating, but prior to that I didn't really cover my tracks, and I'm fairly certain they give exactly zero fucks about what people with business class do with their line.
