If you think “you know the reason” and that “the graphs are wrong”, we are sorry but we are unable to help. The graphs may sometimes be inaccurate, as alongside the counters they are not updated constantly, but if they show a spike, in most cases you can be certain one exists.
If you think there is something wrong with the server/account you are on, you can try creating a new hosting account from your client area and see if the issue replicates there as well. I’d recommend generating a new, different random subdomain, but you could try using your old one as well and see how it goes.
