This was changed about 6 months ago(?) due to complaints that there were too few people playing in tournaments making it difficult to fulfill the top 3 finish daily quest since tours cancel if less than 3 entries. Now every tournament spans all the servers. Take care jumping in a few seconds before the start, sometimes it takes a longer time than that to load the tournament. Good luck to you in your venture ottoman. Try early morning (3:00 - 5:00am) GMT in the middle of the week, player totals are typically lowest then.
