Charter Communications experienced a “widespread” outage of its Internet network Saturday, but service was restored Sunday, said a company spokesman. The cause of the outage is under investigation, he said. Media reports linked the outage to a possible attack on Charter’s Domain Name System (DNS) infrastructure. Charter hasn’t confirmed that its DNS infrastructure was compromised, said ICANN in a statement. “We don’t have information that the issue has gone beyond Charter.” Because the DNS has “notoriously had flaws,” it’s an “interesting target for an attacker that wants to attack infrastructure in the U.S.,” said Tyler Shields, senior mobile and application security analyst at market research firm Forrester, in an interview. Shields said it was too early to identify the nature of Charter’s Internet failure.
