We are checking a DNS server issue now! Looks like there is a problem with our hosts DNS records.
I wish I had known sooner that others could not get onĀ , I initially thought it was a problem with my IP address being blocked somewhere.
I would suggest you signup to the
http://www.auscert.org.au/ bulletins which is the accurate computer/IT threats register across all IT technologies. Otherwise just keep an eye on the webpage regularly.
The latest update on the 'DNS Cache Poisoning' was issued by AusCert on 22/08/2008 ref 'ESB-2008.0821'.
The company I work for issued a USA based notification worldwide on the 24/07/2008. Refer
http://www.kb.cert.org/vuls/id/800113 (I work for a different company that uses the resources to verify the threat). Checks/upgrades to client infrastructure was completed shortly after to protect their IT systems.
The Microsoft patch file fix MS08-037 had been issued on the 08/07/2008, so the threat was affecting people who had not patched & other technologies. The Novell patch was issued approx 17/07/2008.
For other people, DNS (Domain Naming System) is the internet protocol that enables you to type in a name address in your internet browser (eg
www.safirefighter.com). DNS will then interpret the name to the correct servers unique IP address and thus connect you.
So if the worldwide DNS system stopped, no internet or computer communication.
