Our web hosting server has just upgraded its service yesterday. When I checked into the cPanel, it was noticed that the Server was updated to use Apache 2.2.15 and PHP 5.2.13 on April 30th, 2010.
Unfortunately, this caused some issue to our hosting service – it brought down the main website, rendering it inaccessible to the public. We acted promptly to deal with the situation and our technicians are on track to get it back up and running within the next hour.
