New Zealand’s stock exchange is battling to restore services after cyber attacks shuttered the market for a third straight day, frustrating investors who were unable to trade amid a busy company earnings season.

The NZ$204 billion ($135 billion) market, which is nearing a record high, was unable to reopen Thursday after the exchange’s website was again hit with a distributed-denial-of-service attack that floods a network with Internet traffic and disrupts services. Officials have declined to speculate on the source of the attack, other than saying it’s coming from offshore.
