More to my issue, firefox also became unusable with this site, got to the point where even if I did get a page open it froze when trying to post. Tried three other computers on my network ( all chrome / win 10 ) same shit, page wouldn't load / drops connection, either way unusable.
In frustration I replaced my Router / modem ( Netgear AC1200 ) with the Telstra supplied unit. Problem gone!
Pages loading quickly no issues at all!
Got me f**ked, the Netgear worked fine on every other site, but this one?
