It says its entire Doha-based network is undergoing 'continual hacking attempts'.
"These attempts are gaining intensity and taking various forms", the channel says in a statement.
The network has been affected in recent days after neighbouring nations cut of ties with Qatar, where it is based.
Saudi Arabia, Egypt, the United Arab Emirates (UAE) and Bahrain have announced the withdrawal of their diplomats from the country, with Saudi Arabia accusing Qatar of backing militant groups and spreading their ideology.
The UAE has also blocked access to a series of Qatari media websites, including those of Al Jazeera.
Saudi Arabia has closed the Riyadh office of Al Jazeera, and Jordan has revoked the license of the media network.

The cause or source of the attack is not known.
