Gigabit Speed Upgrade in West Michigan?

[awcricket]

I am trying to find out if higher speeds are avilable in my area. I live in Michigan, Zip code 49441.

I currently have 200Mbps. It looks like 600 might be avialble, but I'm also curious if gigabit is available. When I call in, noone seems to know what I'm asking about.

Also, I tried to purchase online myself, but it seems like the only way to get the 600Mbps is to get the security system, which I'm not interested in.

Any help would be appreciated.

What does it say here on your local rate card ?;

Thank you! The first link to the rate card shows blast! As the highest, Which is what I have now. But the second link says 600Mbps is available. Would love to get that if I can.
