NSI Bulletin 098-009 | Whois problems

["David H. Holtzman" <dholtz () internic net>]

We've recently experienced two separate problems with whois
which may have resulted in slow response and in one case a
24 hour delay in propagation of updates.  The first and primary
cause was due to a denial of service attack at whois.  The
initiating location has been temporarily disabled from access
to the infrastructure.  The second cause was due to excessive
internal loading on the back end data base this morning.  
Those activities have been discontinued.
