Shady location for surfers (4,3)

I believe the answer is:

dark web

'surfers' is the definition.
I know that 'surfers' relates to this answer.

'shady location' is the wordplay.
'shady' becomes 'dark' (similar in meaning).
'location' becomes 'web' (I can't justify this - if you can you should believe this answer much more).
'dark'+'web'='DARK WEB'

'for' is the link.

I've seen this clue in The Guardian.
