Root DNS servers

Does anyone know what is currently happening with the root DNS servers?
I'm currently unable to do A and MX lookups on some domains while my
service providers DNS server appears to be ok ...

well, not speaking for the rest of them...
  we seem to be answering every legal/legitimate
  query that we receive.

  why do you think your problem has -anything- to do
  with the root server system?
