The screenshot at the top of the article shows it is classical time control. On lichess that means games are expected to last 25 minutes or longer[1] (the shortest classical controls are 25+0 and 15+15).

It's also worth noting that on lichess (and online chess in general) the fast time control pools are more competitive, so reaching 2000 in Blitz is much more difficult (for most people) than reaching 2000 in Classical.
