Elon Musk's X hit by waves of outages in what he claims is 'a massive
cyberattack'

Elon Musk's X has been hit by three waves of outages since this
morning, which the billionaire claims was due to a cyberattack.

 Musk posted on X that he believes "a large, coordinated group and/or
a country is involved," though the source of motivation behind the
attack wasn't confirmed. Musk also replied "Yes" to a post on X
suggesting people are trying to silence the billionaire and his
platform, although no further details about the service disruption,
including whether it was caused by a targeted attack, have been
revealed.

Eric Noonan, CEO of cybersecurity provider CyberSheath, told CNN it's
likely too early to tell if an attack caused the issues.
