Re: G.fail - Try getting that on Alu
We have Alu in our village, works ok for VDSL when it isn't underwater, being knocked about by Openreach engineers, the temperature is too hot and it expands and joints pop, or it is too cold and they simply fall apart.
Yes we have brief periods of nothing going wrong and get around 60mbs at 500m, then weeks of hell as no one can work out what meteorological based issue has befallen us. !
Putting GFast over that will probably just melt it once and for all.
