I've never gotten to travel anywhere fun for work, just a week in Columbus Ohio. I was supposed to go to Dublin for a week at one point, but that trip fell through at the last minute.
My company's data centers are in:
New Jersey (our New York City DC)
Los Angeles
Denver
Amsterdam
Frankfurt
Singapore
I love how our DCs are in major cities and some where the green is legal
There was talk about opening one in Las Vegas but management said that would not end well for the DC team. Tokyo is the next datacenter for us as rumored. I still have not gone to Singapore, but been to all the rest many times.
