Nintendo has confirmed that Pokémon GO will not release in additional territories any time soon according to Niantic Labs boss, John Hanke.
Speaking to Business Insider Hanke confirmed that due to current server issues, the
international rollout of the game to countries like the United Kingdom and the Netherlands is “paused until we’re comfortable”
Thank you for your patience. We have been working to fix the server issues. We will continue rolling out #PokemonGO to new countries soon.

The game saw a soft launch in Australia and New Zealand and on the 7th July it launched in the US. The app proved so popular that the servers were unable to maintain the player numbers and have been suffering frequent outages.
The kind of outages seen suggest that Niantic aren’t using auto scaling groups which cloud based systems at Amazon Web Services and Microsoft Azure offer and can allow games to automatically keep ahead of demand. Werner Vogels, CTO at Amazon offered help in this area
