Web host Go Daddy has denied an outage which affected potentially millions of sites on Monday was caused by a hack.
It said the outage was instead caused by internal technical malfunctions.
"The service outage ... was not a hack and it was not a denial of service attack," interim chief executive Scott Wagner said in a statement. "We have determined the service outage was due to a series of internal network events that corrupted router data tables."
But the attacker, using the handle @AnonymousOwn3r, posted a link to what they said was source code stolen from the company during the attack.
However further research by Twitter users revealed the posted code was identical to that uploaded to a Google Project Hosting page.
