"Record-Breaking Jackpots and Lottery Changes: What's Happening in Pennsylvania"

The Pennsylvania Lottery has halted sales for Mega Millions and Powerball draws as it undergoes a system upgrade, affecting ticket purchases at retail locations and online. The upgrade, involving a complete computer system transition, is expected to be completed in time for Wednesday's Powerball draw, which is set to reach $687 million. The Mega Millions draw will proceed as scheduled, but only tickets purchased before the upgrade are eligible. The lottery advises that claims processing and coupon redemption will be delayed during March due to the upgrades.
