As Lance Tatman pointed out, load-balancing only works between

factor in planning what kind of wide-area connectivity to use to join
two groups of switches. A single 400Mb/s aggregate might perform much
better than a pair of 200Mb/s aggregates.

    Better performance, but worse reliability?

    The single 400Mb/s is, after all, a single point of failure, no?

To true.  Would you care to cover the cost of replicating the 400Mbp/s
to build in better reliability?  It appears that the owners/operators of
MAE-West are selecting an optimization path based on the assumption that
outages are infrequent and can be quickly corrected.

Both assumputions have been repeatedly proven false BY MFS.
