Well as its intermittent, its like taking your car to a garage and saying its misfiring at times, but not all the time. If its ok when you take it you wind up looking a *%$*.
If it totally breaks down, its easy to find, otherwise its the sort of state we are in now.
When the TS guy tested mine it seemed ok, but only an hour ago this page took ages to load, and so did many others.
Now its fine.
