Is it better "on request" or "upon request"?
Ex: Internet connection is on request or Internet connection is upon request?

Question

Answer

There is no difference between the two phrases, just as there is no difference in meaning between 'on' and 'upon'. 'Upon' is slightly more formal than the everyday word 'on', and tends to be used in fixed phrases such as 'upon request' - but basically the meaning is the same.

Answer

The phrasing I hear most often is "internet connection is available upon request"
