Anyone who has visited Good Old Games or GOG.com recently would've noticed the above message. The message states that they are "closing down the service" and "putting the era behind [them] as a new challenge awaits." They also mentioned that they were putting "in place a solution to allow everyone to re-download their games".
At first there was a lot of specualation going around that perhaps GOG.com was sued, worse that DRM-free games is probably not a profitable strategy after all, despite the popularity of the site.
However, it has been suggested by Kotaku that the message is in fact a marketing ploy (one in very poor taste I might add) and the Facebook group mentions that there will be an update on what is in store for the "new" GOG tomorrow.
Indeed if you re-read the message it does hint towards a new and better GOG.com - hopefully they'll fix the broken game suggestions voting applet!
UPDATE (21/09/2010): A new message has been put up saying that everyone will know more from management on Wednesday. Apparently the site has been closed due to "business and technical reasons".
UPDATE (22/09/2010): GOG are apparently going to release an official statement later today. They also posted the above video on YouTube.
