"We're often hit by cyber attacks but this is a big one,"
The European Commission has apparantly shut down external access to e-mail and the institutions' intranet.
Staff have been asked to change their passwords.
Antony Gravili, spokesman for the security and information technology commissioner said,
"We are already taking urgent measures to tackle this. An inquiry's been launched. This isn't unusual as the commission is frequently targeted."
Mr Gravili added that he had no information the attack had been linked to the EU summit.
France's finance ministry in Paris was recently targeted in December 2010 at the G20.
