CCP Explorer has stated that the first ever client patch has been added without the need for downtime and a server reboot. CCP, many years ago, had stated that they ultimately aim to eliminate downtime and the pesky advantages or disadvantages it renders, Explorer explains that this is a client side patch rather than a server one meaning for a brief period of time, there were multiple versions of Eve running simultaneously on Tranquillity.
Currently, downtime serves to install patches, both client and server side however the main focus of it is to remove excess cans/wrecks/grids from space that cause unnecessary server load. Downtime has however been responsible for the ending of battles, saving of capitals, and other preventions of damages that otherwise would have been suffered had the server not gone down.
Explorer goes on to explain over Twitter how this is a big step in the eventual removal of downtime all together and explains how the new system will allow for CCP to have a more effective and rapid response to technical emergencies and an overall more fluid updating system.
Will you be happy to see downtime go? Or will your supers no longer be safe? One thing is for certain: Aussies everywhere shall rejoice.
