Victoria's Country Fire Authority (CFA) website is running normally again after the page that provides fire warnings crashed earlier on Wednesday.
The site was slow or unable to load information for several hours.
The ABC reports some warnings had to be issued manually and an investigation is underway to determine what caused the problem.
The CFA says community safety was not jeopardised.
State Emergency Services Minister Bob Cameron says people should never rely only on the CFA website but should obtain their information from a variety of sources including radio, have a fire plan, and leave early.
Meanwhile, a fire in Victoria's wheat belt has been brought under control.
The ABC says more than 70 firefighters took over an hour to contain the 20ha blaze in farmland at Dimboola as temperatures nudged 40 deg C in the state's west.
It is one of 119 fires that broke out across the state on Wednesday afternoon.
