I don't think this attack comes from a publishing company, at least it doesn't make sense to me. Think that, given Abandonia's stance towards the companies, if they want it to be withdrawn a download whose copyright they own, they only have to ask and Ab will comply, so there's no need to involve oneself in a crime liable to prosecution as 'Horseman said. And I understand that this denial or service is causing Ab's hosting provider some huge financial loss, so if they get their paws over the culprit some day they'll claim their (financial) due. No it makes no sense.
As for HOTU, I think it's also friendly to the companies. Anyway the gal in charge is from Thailand, so is Lulu (Merry Xmas 'n prosperous New Year BTW
) and she said that some earthquakes have knocked down the Internet there. I don't actually know whether HOTU's server is actually in Thailand, but anyway HOTU was always cloggy for me, and a little time ago it went totally down because of server problems.
Plus Kosta said it, the attack harming Ab was NOT directed towards Ab's server, but towards a server which happens to share its connection with Ab's. The same way we don't know anything about that server, the one attacking it won't know about Ab.
Anyway I'm glad there's a solution coming in that will work in a given time whatever the circumstances.
