Summary Box: Poland defends stance post Web attack

GOING FORWARD: Polish officials vow to stick to plans to sign an international copyright treaty that has outraged Internet activists and prompted an attack on government websites.

THE TREATY: The government says signing the Anti-Counterfeiting Trade Agreement, or ACTA, would not hamper Internet usage. Critics fear it could lead to censorship online.

THE ATTACKS: Following a threat from a Twitter account using the name “AnonymousWiki,” the websites of the prime minister, parliament and other government offices were unreachable or sluggish on Sunday.
