Roger Communications will spend C$263 ($203m) on splitting its wireless and wireline networks following a damaging outage last month.

The telco couldn't give an economic estimate for how much the outages cost, but outlined plans to better combat future outages. Rogers Communications initially expected it would cost C$250m ($193m) to split the networks.

The significant outage lasted for 19 hours and took place on July 8, impacting users in Toronto, Ottawa, Montreal, and elsewhere.

This outage was triggered by a coding error during an update to its network core that led to a series of cascading issues, according to the operator.

It left some users unable to dial 911, while ATMs and other payment services were also impacted during the outages and even grounded some flights. The outages impacted all of its roughly 10 million wireless subscribers and 2.25 million retail Internet subscribers.

However Rogers Communications was not able to quantify the economic result, according to Global News, which reported that these comments were made in a letter that was requested by the Canadian Radio-television and Telecommunications Commission (CRTC).

In the aftermath of the outages, Rogers Communications detailed plans to invest C$10bn ($7.74bn) in the next three years to minimize the chances of further outages. This spend would focus around AI and testing.

Rogers Communications' proposed merger with rival Shaw Communications edged a step closer last week after the two companies finalized an agreement over the sale of Freedom Mobile to Quebecor subsidiary Videotron.

The proposed merger had been met with opposition, but the finalizing of the agreement is expected to pave the way for the merger.
