Firewall/Server maintenance

Just an FYI....
We are currently working on a new firewall project and will be taking the website/server offline for a couple of hours tomorrow morning.
We will be down from 0830am CST Feb. 8th until 1130am the same day.
This should not affect anything other than the site being down for a little while and no data will be lost.
We really shouldn't require this length of time but are accounting for the unexpected.
