compaq.com strangeness?

Seems like NSI lost (or deleted) the compaq.com delegation from
a.root-servers.net. This could be for non-payment of the domain,
or one of NSI's frequent problems with the master databases....

| We had some complaints that users couldn't get to www.compaq.com today.
| It turns out to be a DNS resolution issue, apparently.
|
| If I do an nslookup on the compaq.com domain, I get what appears to be
| the information for .com:
|
| dns# nslookup
| Default Server: dns.heurikon.com
| Address: 192.48.244.69
|
| > set q=any
| > compaq.com
| Server: dns.heurikon.com
| Address: 192.48.244.69
|
| com
| origin = A.ROOT-SERVERS.NET
| mail addr = hostmaster.internic.NET
| serial = 2000060601
| refresh = 1800 (30M)
| retry = 900 (15M)
| expire = 604800 (1W)
| minimum ttl = 86400 (1D)
|
|
| However, all other domains appear to resolve fine, and also compaq.com
| doesn't seem to have any problems when I try it from an external ISP. It
| also works fine within nslookup when I specify a different external
| server (rather than our master DNS server).
|
| Our root.cache hints file is up to date, and we don't seem to have any
| loss of connectivity to anyplace (specifying the IP instead of the
| hostname for www.compaq.com works fine), and this appears to be the only
| affected domain.
|
| I grepped through all my DNS config and zone files looking for
| compaq.com (perhaps something was munged on our server?), and find
| nothing.
|
| Any ideas?
|
| thanks!
