> Rogers staff relied on the company’s own mobile and Internet services for connectivity to communicate among themselves. When both the wireless and wireline networks failed, Rogers staff, especially critical incident management staff, were not able to communicate effectively during the early hours of the outage. Rogers had to send Subscriber Identity Module (SIM) cards from other mobile network operators to its remote sites to enable its staff with wireless connectivity to communicate with each other

ooops. that's actually quite funny

in case you didn't know, Rogers is one of canada's "big 3" telecom providers. The outage in 2022 basically crippled our economy for a couple days (most ATMs / interac didn't work)
