What is better-DS3 or 100MB Ethernet from large ISP?
A Ethernet is far superior to DS3’s these days. First, if they can offer the 100M service, they have fiber to your area. You’ll save money on the port and the bandwidth on the carrier side, and also you won’t need to purchase a DS3 card for your gear. Further, its gives you a nice path to speeds above 100M if you need it. As far as “sharing a pipe” as mentioned above, its all hauled back to the carrier via fiber. The only thing you need to worry about for Internet access is peering points, but it’ll be the same issue if you’re DS3 or 100M. So, take the 100M and don’t look back.
