I also had one to ti.com bounce.

At about 9:30 UTC h.root-servers.net was returning NXDOMAIN for most though not all .com domains. For example, amazon.com and netsol.com were broken. msrl.com worked, but all of its nameservers are in .net; ibm.com worked, but all of its nameservers are within ibm.com and are covered by glue records. The pattern seemed to be that any domain with all of its nameservers in .com but outside of its own zone would fail to resolve from h.root-servers.net. I only tried about a dozen domains so the actual pattern may have been different. I sent a mail this morning to hostmaster@internic.net (with no response of course, but that's the SOA contact for .) and cc'd to nanog (but I had neglected to subscribe to nanog-post). It's interesting that there was no mention of this outage, which caused hard mail bounces and other problems. -- Shields.
