I'm considering my company's options for point-to-point fiber service between our location in Southern Oregon (Medford area) and our main data center in Northern California (North Bay Area, specifically). It is presently on AT&T's MPLS service but the latency is pretty bad.
The building in Oregon already has quite a bit of CenturyLink fiber in it to deliver the T1s. CenturyLink has some presence in the Bay Area already so I may be able to setup a link between the two sites via an intermediate POP connection elsewhere in the Bay Area. Charter is also in the building - actually delivering coax for egress Internet service but their fiber node is not far and Charter has always seemed willing to deliver services to us cheaply. Charter's network presence in California is considerably smaller but it does exist.
The more I look at it I'm thinking it will probably end up being too expensive but I'm still curious what the experiences are out there with these kinds of services and what the pricing tends to be for these inter-LATA long-haul fiber circuits. Also DS3 or OCx services may be more financially feasible but I'm still curious what Ethernet Private Line might run us.
