I was seeing NXDOMAIN errors, so I wonder if they had a DNS outage of some sort??

Were you using host(1)? Please don't, and use dig(1) instead. There were as far as I know at no point NXDOMAINs being returned, but due to the SERVFAILs host(1) was silently appending your local search domain to your query which would lead to incorrect NXDOMAIN output. -- Niels.
