GCSB need to fix their equipment

Stuff reports:

A mysterious low-pitched humming sound has been troubling some Wellington residents for the last few days and it seems no-one has any idea what it might be.

The Wellington City Council has had several calls over the past few days with the most recent being about 5am today.

Spokesman Richard MacLean said the complaints had been coming in from , Newtown and Mt Cook residents. “We are interested to hear if starts to become a constant thing. We are keeping our ear to the ground.”

It's just feedback from the underground surveillance system, as they change frequencies to go digital!
