Boxing fans who waited five long years to see Floyd Mayweather Jr. and Manny Pacquiao duke it out had to wait a little longer Saturday night as a rush of pay-per-view orders caused technical difficulties that led to a delay of the fight.

While the fight had no official start time, Time Warner Inc.’s HBO and CBS Corp. ’s Showtime, which were partners on the telecast, were hoping for the first punch to be thrown no later than 11:15 p.m. Eastern time.

Instead, it kicked off about midnight. Often big boxing matches don’t start until after midnight but the Mayweather-Pacquiao bout garnered attention far beyond hard-core fans, and the promoters and networks didn’t want to frustrate TV viewers with a very late start.

Many major pay-TV distributors, including satellite broadcaster DirecTV , Cox Communications Inc. and Time Warner Cable Inc., had challenges with heavy demand for the fight, which led to glitches and slow processing of orders. Subscribers took to Twitter to complain and some distributors, including Charter Communications Inc., responded that they were aware of the problem and were working to fix it.

No announcements about the cause of the delay were made in the arena, but on the telecast, the TV issues were acknowledged.
