Were you able to resolve names to IP addresses and then unable to reach those addresses? If so this would not be a DNS failure but sounds more like a routing problem. Or were you unable to resolve names but could reach any (previously known) IP addresses? This would be a DNS outage and if you use names for mail/ping/web then would obviously mean you could not reach those services (but only because you didn't know the address. How this would occur if you had 3 DNS servers configured is strange, if one was not responding then the others whould be used. Why the 27th of each month? Why not? Maybe they update user accounts on a monthly basis and it is not a transparent process, who knows.
