Kim Dotcom has apologised to users of his new website, Mega, for the "poor service quality".
The new "legal" cloud storage website went live in New Zealand at 6.48am local time on Sunday and Dotcom threw a huge launch party at his Coatesville mansion, north of Auckland, to celebrate.
However, Dotcom took to Twitter on Tuesday to say sorry to Mega users who have experienced problems with the website.
"The massive global PR around the Mega launch is simply to big to handle for our start-up. I apologize for poor service quality," he tweeted.
"We are working 24/7 and expect normal operations within 48 hours. Lesson learned... No fancy launch event for Megabox."
Dotcom hopes to launch Megabox, a music service, in about six months' time.
But Dotcom was coy about just how many people have registered as Mega users.
"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," he also tweeted.
At the Mega launch and press conference on Sunday, Dotcom told media and invited guests more than one million people had visited Mega within 14 hours of the site's launch and about 500,000 had registered as users.
"What we are offering is a smarter, faster and more secure way of cloud storage and we are fully assured by our legal team that we are in compliance with the law," he said.
