Service provider broadcast its URL: it contains glitches initially (9)
I believe the answer is:
liturgist
'service provider' is the definition.
(I've seen this before)
'broadcast its url it contains glitches initially' is the wordplay.
'broadcast' is an anagram indicator (letters scattered or cast around).
'contains' indicates putting letters inside.
'initially' indicates taking the first letters.
The first letter of 'glitches' is 'g'.
'its'+'url'+'it'='itsurlit'
'itsurlit' with letters rearranged gives 'liturist'.
'liturist' enclosing 'g' is 'LITURGIST'.
(Other definitions for liturgist that I've seen before include "Performer of ritual" , "leader of service" , "service provider" .)
