I have some additional information that's making me think what I saw on Saturday was just a coincidence. We have two DNS servers that were unable to resolve external addresses beginning around 4:00 PM MST on Saturday, but I found out that they both had just been rebooted. We use some version of BIND on Solaris 9 and it was verified that named was running, yet external names would not resolve for a few hours. External names began to resolve in a few hours with no intervention on our part. BIND gurus, any idea why this might have occurred? If named is running and internal names resolve *and* there are no problems with Internet connectivity, what might cause external lookups to timeout for a few hours only to resolve spontaneously? It seems a little strange and I'm sure there's some important information that I'm missing that would make it all makes sense. Thanks, John --
