Has anybody noticed any problems this morning with some of the root name servers? (Particularly a.root-servers.net?)

No, but UUnet sure is funky today. Seems their load balancing with CEF is broken again (like every 3-4 weeks), and it seems to occur between EWR1 and DCA1.Alter.net routes more often than elsewhere. General symptom: machines (local or remote) in the same subnets can/cannot reach remote machines depending on whether the IP number (source or destination) is odd or even, or the path (forward or return) to remote machines is different depending, once again, on whether IP addresses are odd or even. That leaves the question: how does CEF decide which circuit to shove a packet into ? 3 ping runs from 3 separate, unloaded machines on the same subnet, with the last octet of their IP's being .6 , .3 and .5) --- www.yahoo.com ping statistics --- 55 packets transmitted, 55 packets received, 0% packet loss round-trip min/avg/max = 481.775/528.385/586.649 ms --- www.yahoo.com ping statistics --- 67 packets transmitted, 63 packets received, 5% packet loss round-trip min/avg/max = 216.211/271.548/310.969 ms --- www.yahoo.com ping statistics --- 62 packets transmitted, 62 packets received, 0% packet loss round-trip min/avg/max = 83.303/130.738/174.111 ms And the same machines (sequence preserved) pinging Netscape: Message from kai@saturn.speedus.com on ttyp0 at 12:16 ... --- www.netscape.com ping statistics --- 91 packets transmitted, 87 packets received, 4% packet loss round-trip min/avg/max = 11.679/23.564/55.384 ms --- www.netscape.com ping statistics --- 84 packets transmitted, 84 packets received, 0% packet loss round-trip min/avg/max = 209.768/241.706/270.967 ms --- www.netscape.com ping statistics --- 106 packets transmitted, 104 packets received, 1% packet loss round-trip min/avg/max = 1637.63/1688.41/1722.27 ms The same is true for a whole boatload of other sites (tested from a UUnet-connected site as well as a Globix-connected site), whether they are webservers with Local Director on the front end, or small 2501's tucked away under someone's staircase. Now try to explain that to a UUnet "Did you power-cycle your router? It must be your telco's problem!" Customer Service person - I won't waste my time :)
