Overloading nodes?

I've had 30/5 internet service with TWC for a few years now.  Generally it has been reliable and giving me in the neightborhood of 36/6.  Lately, I seen it dip to the low 20's upload, and be very erratic.  During speed tests it will jump all over the place IRT to speed. 

 

Wondering if by replacing the generally lower speed TWC connections with the Spectrum 60 Mbps basic they are slowly overloading the existing nodes.

As for your speed, you're thinking upside down;  36 x 6 is the 30 Mbps download, 5 up package. 

Your suspicion is not quite the documented root cause, but it is a contributor.  TWC->Spectrum is refusing to pay their contracted IXPs (Internet eXchange Provider) extra for carrying the rising volumes of data transfer during busy hours, so those carriers are slowing traffic to match what they are getting paid for. 

Then, as you correctly suspect,  every new internet customer adds to the traffic load and makes the existing (several years now) bottlenecks worse for everyone.  It affects the highest speed customers first, but eventually hurts even the 3 x 1 ELP subscribers when the overall demand far exceeds the contracted data volume.

Yeah,  slip of the keyboard.  Meant 'dip into the low 20 's download'.   So the bottleneck is higher up the chain than I suspected.

you need to make sure you have an 8x4 or 16x4 modem and all the channels are good.

When you or the node neighbors have bad ones, the entire node suffers.

SB6141 still hanging in there.  Had an outage yesterday, so log doesn't say much.

 

(how the heck does one import the modem signal page or other .jpg into this goofy forum software?)

 

All 8 downstream signal levels at -3 dBmV,  SNR 38 dB.  Upstream 41, 42, 44, 45 dBmV

rt click copy and paste...

 Of course that's using a real OS, not the current cloud based crap...
