Communications were slow for the Sioux Falls Catholic Schools yesterday.
A hacker broke into the school's system, halting all internet, phone and email communications.
Superintendent Tom Lorang says it slowed some processes -- including online testing for some students -- but it didn't stop the district from getting work done.
Lorang wouldn't say if the security breach was done by a student, but he did say the incident was under investigation.
