This, thankfully, doesn’t affect me or anything I look after.

However, I imagine that some of the larger Churches out there will be running their own DNS systems that are likely to be affected. Long and short, whether your DNS is Unix, MS or some other variant you need to patch it and now.

For those, like me, whom want the details then go here:

If you want some background info, then take a wander over to Arbor Networks take on it or even go and hear from the man behind DNS, Paul Mockapetris, over at Network World which may require you to create a free account before reading.
