Cyflymu Cymru sydd wedi darparu gwasanaethau band eang i hanner yr holl gartrefi a’r busnesau ar draws Cymru sy’n gallu manteisio bellach ar fand eang ffeibr cyflym. Dim ond mewn ardaloedd lle nad oedd gan gwmnïau masnachol unrhyw gynlluniau i ddarparu band eang yr oedd rhaglen Cyflymu Cymru ar gael. O gyfuno’r rhaglen honno â’r gwasanaethau a ddarparwyd yn fasnachol, mae’r dechnoleg ar gael bellach i fwyafrif llethol yr adeiladau yng Nghymru.
