In this case it was about once a year and it was the only cable directly connecting the two locations. There was one occasion where there was a break only months after one was finally repaired, really frustrating. There are more cables taking that route now, so a bit of redundancy. Most of the time I'd find out officially via network operators bulletin boards (i.e. those looking after AS and IXs) there wouldn't be anything reported in the local news because, for most people, as this article alludes to, the content edge servers they actually connect to are pretty close, both physically (distance) and virtually (hops).
