IMPORTANT: The Big DOS (Denial of Service) attack on HistoryReviewed and AfricanCrisis

[One of the regular readers of my site sent me this interesting feedback regarding the downtime of my website. This is definitely the longest downtime I think I've ever had. Sometimes various people who hate my website also leave messages for me in various ways. Someone used this as his email address: iwanttotorturenazifucks and as his name he wrote: Exterminate Nazi Vermin – so these are the types of things they write. See the note below from the Canadian reader. I'm grateful for this feedback. Normally they just try to hack my websites. But I suspect that they may be changing tactics to do DOS – Denial of Service. They did hack certain software plugins on both my sites too, which I fixed. Jan]

I am in Canada so your night is day for me. Anyways your website was down for at least 6 hours total yesterday and so was Africancrisis, although I think Africancrisis might have been down a little shorter, maybe 4 hours.
