From my data centre: Dear Customer, You are receiving this e-mail because you are currently located in our Dallas Texas data centre. On Sunday, January 13th, we will be upgrading PHP 4 on your server from version 4.4.7 to version 4.4.8. As this upgrade is mostly just bug fixes and security patches, it should not cause any problems once completed. More information can be found at the forum thread that is linked below.
