As you are aware, we have two servers – acswebservices and acs-webhosting.  For those of you hosted at acs-webhosting there will be scheduled maintenance at 5pm Thursday 20th November AEST.

This is the message I’ve received:

We will be performing scheduled maintenance on your server on November 19th @ 10:00 PM CST (20th @5pm AEST). During this time we will be upgrading our Apache web server to version 2.2.10 (from 1.3.4x). We will also be upgrading the operating system from CentOS 4.7 to CentOS 5.2.

This upgrade will allow us to provide you with a higher level of performance and security. During the upgrade we will also be installing a new set of mod_security rules which will add to the overall protection our clients websites. We will also be upgrading our firewall software which help deflect distributed denial of service attacks and ensure that your sites are kept functioning at optimal levels.

The server will stay online during this time however while the Apache service is recompiled your websites and your client websites will be unavailable for an estimated 30-45 minutes. During this time an unbranded, generic “Under Maintenance” page will be displayed instead of your normal content.

Please take note of this time so you are aware that your site might be temporarily disabled for a short time.
