UB-79 had a displacement of 516 t (508 long tons) while surfaced and 648 t (638 long tons) when submerged. Her engines enabled her to travel at 13.6 knots (25.2 km/h; 15.7 mph) when surfaced and 7.8 knots (14.4 km/h; 9.0 mph) when submerged.

gollark: Keep the one which is `fastcgi_pass`ing to whatever your PHP-FPM-or-whatever thing is on.
gollark: Per location.
gollark: Well, you can only have one fastcgi_pass line.
gollark: You have two fastcgi_pass directives and shouldn't.
gollark: `"fastcgi_pass" directive is duplicate` and it even tells yo uthe file and line.
