Spark Sport's website was offline for more than an hour from 10.30am this morning - on the final day of its $60 Rugby World Cup Tournament Pass earlybird deal.
After today, punters will have to pay $80, rising to $90 for those who wait until September.
A spokesman told the Herald the outage was 'planned maintenance."
However, the timing is curious, and when the Herald visited it using various devices, Spark Sport was showing only a blank screen, not any planned maintenance message.
Websites typically carry out maintenance after hours.
