Wolfram Alpha uses the same server farm as the Alpha interface provided by Mathematica proper, and it is entirely possible that during times of heavy load from the people who paid money to access the Alpha API in Mathematica, the people using the free web interface have a lower priority in the system. I bought Mathematica Home Edition, and I get several thousand API calls a month, but if I had bought the more expensive version I would have many more.

If you are working at a large company it is possible that others on your internet connection have been using Alpha and used up the time allotted to that IP address.
