SATURDAY, MARCH 8
PHP 5.5 Upgrade Scheduled for Wednesday March 12 on all Free Hosting Servers1 month ago
We will be upgrading PHP on all the Free Hosting servers, including Illuminated, this Wednesday. The upgrade is scheduled to begin at 2:00am UTC, and will likely take several hours. Brief, minimal service interruptions are expected throughout this time frame.
After the upgrade, all Free Servers (absolut, level, vox, and illuminated) will be set to run on PHP 5.5 as the default PHP version. PHP 5.3 and PHP 5.4 will still be available for users who cannot upgrade to PHP 5.5 at this time; instructions on how to switch your PHP version are available
here. For Illuminated, PHP 5.2 will be available in addition to 5.3, 5.4, and 5.5.
Please note that we do not officially support older PHP versions, and we do not guarantee this service from failure. You should always upgrade your scripts so that they run on the most recent version of PHP.
For more information on what sorts of changes you can expect from PHP 5.5, see the
PHP 5.5 Migration Guide on php.net.

I see nothing stating the update is complete. Should I assume that it is still ongoing?
