I am currently in the process of evaluating carriers for future expansion into international regions, primarily Asia, Europe and South America.
I am comfortable with AT&T and Verizon however I would like to make sure I include all the major players and would like your direct feedback and commentary in regards to any of them.
These are the key areas I am concerned with.
Support
Reliability
Flexibility
Complexity
Coverage
I am looking at two deployment options as well if anyone would like to comment.
A single carrier for global connectivity to all sites (mpls etc)
A single carrier for global regional connectivity, and in country/regional carriers for all local offices that funnel back to regional aggregation points.
Could you provide a little more detail as to your requirements? Bandwith, applications (voice, video, etc…) number of sites, that sort of thing. On the surface the first thing that comes to mind is redundancy. You are going to have outages, especially if you have to go that far point to point. The best thing would be to have a second circuit with another carrier on a diverse path. The worst thing is when both the primary circuit and the backup were ordered through the same carrier and both go down during the came fiber cut. Worse still is when they were ordered from two different carriers but carrier B actually bought bandwidth from carrier A resulting in the same outcome.

If this is for redundancy, also keep in mind that most ‘cuts’ occur in the last mile. Unless you are in a major facility with engineered entrance/egress diversity a failure will result in ALL terrestrial links failing. This is a very string argument for a limited bandwidth satellite or EVDO backup link. (Which one depends on many other factors.)
Diverse entrances are standard in telecom hotels and major data centres.
I don’t think you have made the redundancy argument for satellite particularly given the relative expense of transponders vis-a-vis private line capacity on the major routes. However, it could play a role in some cases. Also satellite’s latency is simply too high for the applications of financial firms. Every millisecond of delays costs millions in lost trading profits over the course of a year.
The real failure is relying on just one data centre for backup. Most of the smarter European and North American financial firms now have data centres in both Europe and North America and replicate their data across TransAtlantic links. A lot of large file transfers at night for the hedge funds.
