Possible intermittent downtime, Network Changes Options

[helvick]

All,

We have to implement an ip-address change on the server over the next 12 hours or so. The board may be unreachable briefly in an hour or so and there may be some DNS issues over the next 24 hours. There should not be any extended outages of more than 5 minutes at any point, and I'm hopeful that there wont be any noticeable downtime at all. I've set the DNS TTL to 15 minutes as an advance step, and will be reducing that to 5 minutes for the hour or so around the change. This _should_ propagate out and make it fairly painless.

I'll post an update once the change has been made, or let you know that we've postponed the change if there are any issues that crop up and prevent us switching over.

If I had my way there would be no changes right now, but that's not an option unfortunately.

On the plus side a lot of care is being taken, our hosting provider is double checking things as I type, and while I can't be certain just by looking at a single example, the TTL number reported by your dig query indicates that the preparatory changes in TTL are working as they should.
