There doesn't seem to be an obvious "this is the server that > normal API calls go to" on http://wiki.openstreetmap.org/wiki/Servers. In general, no. The performance of the API depends on both the database and the 3 Rails application servers that handle all the requests (i.e. converting db results into xml documents etc) and a few other things too. Any number of things going wrong can make it go slowly, and some of the graphs look similar under different scenarios so if one chart showing a peak coincides with problems last time it doesn't always follow that the same thing will happen again.
