Shame that Spark lost their bottle and chucked the Springboks game up on Duke. Guess it was inevitable really, had to head off a PR sharkstorm. For what it's worth I had a decent enough experience, three or four slight buffering episodes in the first half and a couple in the second. But nothing major. To be fair I'm not sure how representative that is though, if loads of people had issues despite having adequate internet, then shame on Spark.
Re: sky, a bit shark that last year they had Serie A stuff on the regular channels separate from the now defunct standalone Bein channel, but now it only seems to be scheduled on the Sky Sport 7/Bein channel hence clashing with Bundesliga and La Liga so less live games are shown.
Really enjoyed the rugby comms with Stevenson and Donald, far less stale than the Sky comms which is technically fine but feels rather stale with Marshall et al calling what feels like their 500th test match every time.
Not so much lost their bottle as had a disaster. Watched at a friends with fibre and the first half was almost unwatchable the resolution was in and out of crystal clear HD to so pixellated you couldn't read the score probably 30 or so times, with a couple of 30 second freezes in there for good measure.
edit: Agree the change in commentary was great. I'm not a big fan of Stevenson, but I thought he actually did really well, and I enjoyed Donald's contributions too.
