Why Twitter Trends Are Not Updating?

We update Twitter trends in our database every 30 mins.

So, once the 30 mins passes you will get to see the fresh trends fetched from the Twitter

We also cache the web pages on the server for short interval. Because of this you might see the same last updated time for some time (or in page refresh.)

If this is the case, then please recheck after 5 mins. You will get to see the fresh copy fetched from the server.
