title: Speed from Different EC2 Regions
body: <p>I'm based in the UK, as are all users of my web app, and currently host in the EU-West region.  The US-East region is quite a bit cheaper and I'm using a service from another company that locate their servers in the US-East region (meaning that I'll have data transfer costs between regions if I kept things in the EU). Has much of a speed difference am I likely to see between the two?</p>
  
  <p>(I could do a test myself but I'm hoping someone else has already done it :) )</p>
  
  <p>I'd appreciate insights that anyone has. Thanks in advance</p>
