Ouch! A couple of questions: 1) Is the "7500" the actual number of routers they'll have to upgrade, or are they referring to the Cisco 7500 product line? That's an awful lot of routers to upgrade, so UUnet could have problems for awhile. 2) What could have caused the memory requirements to jump so dramatically? And if it's due to the routing table "for the whole Internet", why weren't others affected?
