That's not what Wikipedia says at all.

> In 1998 Ericsson announced the AXD301 switch, containing over a million lines of Erlang[...].[8] Shortly thereafter, Ericsson Radio Systems banned the in-house use of Erlang for new products, citing a preference for non-proprietary languages. The ban caused Armstrong and others to leave Ericsson.[9] The implementation was open-sourced at the end of the year.[5] Ericsson eventually lifted the ban; it re-hired Armstrong in 2004.[9][...]

> Erlang has now been adopted by companies worldwide, including Nortel and T-Mobile. Erlang is used in Ericsson’s support nodes, and in GPRS, 3G and LTE mobile networks worldwide.[10]

Not to mention

"In 1998 Ericsson announced the AXD301 switch, containing over a million lines of Erlang and reported to achieve a high availability of nine "9"s"

That was the first commercial use of the language. The first commercial use of a 'niche' language, with over a million lines of code, achieved a downtime of just over half a second over 20 years. That's total downtime, too, not just 'unplanned'. And even if you take into account the numbers touted by critics of that quote, of 5 nines...that's still considered world class. For the first damn commercial product.

That's delivering.
