Broadband providers in downtown Chicago

Our company is in a building at 200 w. Monroe and we have difficulty
finding an internet service provider that could at least provide
1Mbps+ Upload bandwidth that is not Cogent Communications.

Is it really this difficult finding a decent internet service provider
in downtown Chicago?

No, it isn't. Unless your building management has an exclusive deal
with Cogent. We have our choice of basically every national Tier-1 and
all the larger regional players around the corner on Monroe.

When you say "broadband", are you trying to source a residential
provider in downtown? I could see that being a challenge.... Take a
look around for a metro-eth based Internet pipes, I'm sure they are
plenty in that area. TWTC might be one to check out if you're against
Cogent [Level3].
