BoardWatch Magazine publishes a summary of country-wide backbone
providers once or twice a year. If you look specifically for this
publication you can get a good overview of which networks connect to
which cities and NAPs ("MAE-East" is a NAP).
Personally, I don't think you're really looking for a solution like
this in the end. You might want to consider pooling data locally at your
collection centers and, as someone already mentioned, replicate this
data to a central source. Then, if you choose to use a web interface
for collection and display of this data, you can have multiple
webservers, each local to the pooled data, and a master server residing
over the central data. With this model, the central repository's
reports could conceivably be impaired by net traffic, but the local
centers, where the data is entered, will remain up to date and
functioning regardless of disasters in other locations or loss of
connectivity.

Exodus is now owned by Cable & Wireless. C & W also bought Digital
Island, so they have some great technology for distribute web sites.
Global Crossing is another Enron, so you best stay away. AboveNet,
which
was always owned by Metromedia Fiber Network (MFN); has been sucked
back
into the parent company. MFN has had and continues to have one of the
best IP networks in the world. Their claim to fame is also that they
run
the MAEs. UUnet has a great network, but they are part of WorldCom,
which is having serious trouble theses days. Savvis has some really
nice
offerings and has weathered the downturn thanks to their monopoly on
finical services networks that their parent company Bridge gave them.
Level3 Communications also has some good stuff these days.
There are plenty of other ISPs and hosting providers, but they really
can't compete with the above list.
