  1. Distributed storage for games you don’t have to worry about

  2. Thousands  of  players  across  the  world  are  playing  and  

    having  a  good  experience  –  in  fact,  more  than  700,000   cities  have  been  built  by  our  players  in  just  24  hours.   But  many  are  experiencing  server  instability  and   consequently,  the  rollout  in  North  America  has  been   challenging.  It's  also  now  evident  that  players  across   Europe  and  Asia  are  experiencing  the  same  frustration.   Our  priority  now  is  to  quickly  and  dramatically  increase   the  number  and  stability  of  our  servers  and,  with  that,   the  number  of  players  who  can  simultaneously  access  the   game.  We  added  servers  today,  and  there  will  be  several   more  added  over  the  weekend.  We're  working  as  hard  as   possible  to  make  sure  everyone  gets  to  experience  the   amazing  game  we  built  in  SimCity.
