I've said it before and I'll say it again - by "core hiding" you take away
important diagnostic tools (traceroute/mtr) from your customers. So *if*
you do that, make sure your monitoring and first-level support is fully
up to speed should you ever have LSP black-holes or packet loss in your
network.
We terminated our contract with Global Crossing because they regularily
had issues in their network (packet loss, high latency, black holes),
traceroute hiding gave us no way to pinpoint the issue, and their
support stuck to the "we can't see anything so there is no problem"
mantra. This combination is completely unacceptable.
