State-sponsored Russian hackers have been accused of forcing Georgian government sites offline in a cyberwar alongside the physical operations.
The Georgian president's official web site, the Ministries of Defence and Foreign Affairs, as well as a number of other government and commercial sites, have all been affected.
In addition, the country's Parliament site has been defaced, with images of the president replaced by pictures of Adolf Hitler.
The Georgian government is calling the attacks a "cyber warfare campaign by Russia".
It is warning people surfing the sites to exercise caution as some information could be diverted to Russian servers.
