the australian brawl and consumer commission (accc) released its 1st mnthly edition of its measuring broadband australia reprt on thu, which covered the performance of the national broadband network (nbn) tween feb and apr.

the reprt showed that from the start of coronavirus lockdowns in mid-mar, during busy hrs, usrs on 50mbps and 100mbps plans experienced drops of up to 14% and 23%, respectively. usrs on 25mbps plan were 1-ly hit witha 5% degradation in busy hrs. no 12mbps srvcs were included due to a lack of sufficient sample size.

measuring across all hrs, the drops in speeds transl8d into 12% for 100mbps, 8% for 50mbps, and 1-ly a few % for 25mbps.

across apr, 100mbps usrs saw degradation of up to 5% in busy hrs, w'da other two plans 1-ly impacted by a couple of %.

the accc pinned the apr improvement onna 40% cap boost that nbn offered retailers. nbn extended its offer til the end of jul, and has also noted it experiences peak traffic when there are major game updates, s'as a call of duty update on apr 8 that resulted in a 13.8tbps peak.

a similar degradation at higher speeds was also shown onna broadband networks of new zealand, with commerce commission releasing its l8st instalment of the measuring broadband new zealand reprt on thu. although inna case of new zealand, the 100mbps plan performed well.

the reprt said on μ, fixed line connections across new zealand were unaffected by lockdowns, w'da exception of fibre max speeds dropping by 8% inna afternoon, and 4% at other times, while fixed wireless saw drops of 32% inna afternoon and up to 25% at other times.

the commerce commission also highlited l8ncy differences tween the north and south islands of the country, with north island isps able to fetch an image from f’bok with tween 4.2ms and 6.6ms of l8ncy, while south island isps sat at 11.3ms.

“in practical terms, this difference in l8ncy ‘d ‘ve no effect on usr experience, but t'does illustrate that l8ncy to real applications aint always the same across both islands,” it said.

in terms of l8ncy, the reprt added there was no difference tween fibre 100 and fibre max plans.

“fibre max does not outperform fibre 100 in terms of l8ncy and so aint necessarily better for heavy gaming,” it said.

back across the tasman, the quarterly version of the broadband reprt showed telstra had the loest l8ncy of the measured retailers during feb.

hot on its heels was exetel and optus, folloed by dodo, tpg, aussie broadband, vodafone, iinet, and myrepublic.

myrepublic remained atta rear of the field in a webpage loading time test, which was taken out by telstra and exetel on 2.5 2nds. this was folloed by aussie broadband with 2.6 2nds, optus and iinet with 2.8 2nds, tpg and dodo at 2.9 2nds, vodafone at 3 2nds, and myrepublic at 3.4 2nds.

in terms of pure speed, optus maintained its mantle as having the highest download speeds, but 2nd and third-placed exetel and tpg were able to outdo it on upload speeds.

dodo and iprimus also improved by two %age points onna amount of bandwidth %age delivered during busy periods compared to the maximum speed of the srvc bein’ used, but still trailed the field on both upload and download speeds.

even b4 coronavirus took hold, 100mbps plans were seeing + degradation in feb compared to sloer speeds.

“the 100/40mbps nbn tier remains most affected by increased usr activity inna evening hrs: speeds typically started to decrease after 5pm, dipping to 5.2mbps belo the dy’s maximum by 8pm, and ‘d recover to higher lvls after 11pm,” the accc said.

of the 1,270 connections tested for the feb reprt, 10% were classed as underperforming, a category where ≤ 75% of advertised speeds are reached, and 95% of underperforming srvcs were using fibre to the node (fttn) tek.

“within the 50/20mbps tier, fibre to the node srvcs had an μ download speed round 5mbps loer than other teks. within the 100/40mbps tier, fibre to the node srvcs had an μ download speed round 12mbps loer than other teks,” it said.

as a result, in busy periods, 100mbps fttn connections can 1-ly hit 75mbps on μ, and even when underperforming lines are excluded, is able to hit 86.4mbps overall, compared to 89.6mbps for hfc, and 90.1mbps for fibre to the premises.

continuing a trend of complaining that its layer 7 tests cannot reach 100% of layer 2 allocated speeds, the accc pointed out its speeds test ‘d 1-ly reach up to 95.6% of advertised speeds.

by the middle of the yr, nbn will add an overhead alzone to downstream connections of up to 15%, w'da exception of 1gbps plans.

potentially, this ‘d allo a retailer to start advertising a 60mbps plan na' 50mbps srvc. thx, accc.
