Expressing an apology for teething problems with his Sunday-launched new file-sharing service mega. co. nz site, Kim Dotcom - the alleged online piracy linchpin, and the founder of the shuttered Megaupload site - said that the overwhelming worldwide interest had virtually inundated the website.

New Zealand-based Dotcom - who was arrested in the world's biggest online piracy case in January last year - said on Tuesday that his new mega. co. nz site had already become so popular that it was facing some technical glitches.

According to the information shared by Dotcom, during the first 14 hours of its launch, the mega. co. nz site attracted approximately one million visitors and over 500,000 registered users.

In a tweet about the early problems being faced by the site due to the overwhelming response, Dotcom, 39, said: "The massive global PR around the #Mega launch is simply too big to handle for our start-up." He also apologized for the "poor service quality" which the users of the site had to face.

Dotcom further added that the issues affecting mega. co. nz were being resolved by his team, which he said was working round the clock. He hoped that the team will be able to get the service running normally within 48 hours.

Meanwhile, refraining from giving an update on the mega. co. nz user figures, Dotcom said: "If I would tell you how many signups we had since the launch you wouldn't believe it. I can't believe it. So, I won't tell you."
