Er mwyn cysylltu’r ychydig eiddo hynny nad yw Cyflymu Cymru neu fenter fasnachol wedi llwyddo i’w cyrraedd, caiff arolwg o’r Farchnad Agored ei chynnal ym mis Tachwedd i weld, fesul eiddo, ble yn union y mae band eang cyflym iawn ar gael.  Defnyddir yr wybodaeth i lywio’r cynllun nesaf a fydd yn dechrau ym mis Ionawr 2018.
In order to reach those few premises not reached by Superfast Cymru or commercial rollout an Open Market review is due to take place in November to establish premises by premises where superfast broadband is available.  This will then inform the next scheme with delivery beginning in January 2018.
