Same here in northwest las vegas, FCC complaint filed, have a tech coming over tomorrow for a line verification. Before the covid crisis it was happening daily between 5PM-10PM. Now it's more like noon to midnight. odog on dslreports said there was some construction commencing on 3/11 on my leg of the cox network (i assume a node split). Still hasn't improved. odog said it was possibly was put off because of the covid pandemic and is checking for me. Hopefully they find something tomorrow, but doubt it. Century link fiber is across the street from me. I'd love to switch.
Here's my original dslreports thread:
