It looks like 701/1239/3356 are permitting 4837 to announce this prefix because:

There is some less-than-great management of the associated IRR data.
It'd be in the best interest of <someone> (Metro Wireless) to start
asking the various IRR's:
  bell - config at in.bell.ca ?
  radb -
  nttcom - job?
  apnic -

to remove the objects in question.
I'm curious why NTT's still holding this record since there's a competing ROA?
