During the Titanfall beta and after the release of the game itself many Optus customers were having difficulties logging onto Titanfall, but Optus now believes it has fixed the situation.
"Our network engineers have continued to investigate the Titanfall access issue that some of our cable broadband customers were experiencing, and over the last few days we implemented a network configuration fix that we believe has resolved the access issue," an Optus spokesperson told Kotaku.
"We are still monitoring traffic to the Titanfall servers to ensure our customers access continues."
On the complaint thread over at the official Optus site, it appears as though most are now able to play Titanfall without issues.
"We’d once again like to thank the customers that got in touch and gave us specifics on their experience with the game," said Optus, "as this really was a great help."
