Obsolete, oversubscribed network and little heed to customer requirements
I was given a committed service date without validating that was even feasible. Sparklight missed that date by over a month because they had no capacity left in the network. I was asked if I needed a modem and said "no, I've got a CM1200 I bought". Turns out they won't allow me to use that modem with static IPs, but they failed to tell me that when I signed up for service. They want me to buy an obsolete and expensive Arris Surfboard DOCSIS 3.0 router instead, then disable 90% of the functionality. I asked why their DNS servers don't implement DNSSEC for added protection against spoofing, and was told there was a problem with Netflix two years ago. Sparklight did no follow-on investigation to confirm that Netflix still has that issue [they don't], so they're basing their decision on information garnered 2 years ago and have not bothered to ensure that it's even still relevant.
Update: I responded last week to the solicitation (below) to look into the issue and resolve it, with all of the requested information and more. True to form, Sparklight never got back to me.
Update 2: I've sent 5 emails complaining about network abuse that's targeting my subnet. I have yet to have the issue acknowledged, much less resolved. I've never worked with a worse MSP in 30+ years. I rated them '1' star out of 5 because zero wasn't an option.
Update 3: I've complained 4 times over as many weeks about receiving NetBIOS Datagram broadcast traffic spoofed as my default gateway. I've not received a response, despite calling the Network Operations Center and bringing my previous email complaints to their attention. I was told someone would look into this and get back to me. Again, endemically underperforming, they failed to do so. Forwarding directed broadcasts has been proscribed since RFC-2644 was published 22 years ago. I'm told I can't operate a standalone modem because that's a security risk, but allowing DDoS amplification of Smurf Attacks isn't? Is there anyone at Sparklight who knows what they're doing?
Citing their own "Network Management Disclosure":
"As described above, Sparklight reserves the right to employ network management practices, e.g., to prevent the distribution of viruses or other malicious code, [...]. As such, Sparklight blocks ports 135, 136, 137, 138, 139 & 448."
If that were true, why would I be seeing this traffic?
Also citing this document:
"A DOCSIS 3.1 or higher modem is required to receive nearly all of Sparklight's speed offerings (8 channel or higher version works best). Although DOCSIS 3.1 modems will operate on our network at this time, customers may experience substantially slower speeds than advertised."
Again, not so. I was told that if I wanted a static IP address, I had to purchase an Arris DOCSIS 3.0 device and couldn't use my Netgear DOCSIS 3.1 modem.
Further, this document references another:
.../115009158227-Which-Cable-Modems-are-Supported-
which states that Netgear CM1200 modems are "recommended", but that's the very device I was told I couldn't use (it's still in the box, alas).
Further:
"Sparklight also employs certain practices to protect the security of our customers and our network from unwanted and harmful activities. These include practices designed to protect our servers against Denial of Service attacks [...]"
Then why am I seeing directed broadcasts on port 138?
And the "Business Internet FAQ" states:
"Sparklight requires customers to use a DOCSIS 3.0 Cable Modem. These modems incorporate the latest cable technology, have the capability to deliver faster internet speeds, and have a longer expected lifetime."
Let's see... DOCSIS 3.0 was released August 2006. Is that when this document was last updated? Because DOCSIS 3.1 was in 2013 (nearly 10 years ago!), and DOCSIS 4.0 will be released some time in 2023.
Jenae Heck: are you out there listening?
Update 4: After asking a few simple questions, like "why do business customers pay more for inferior service with fewer choices?", "who decides what modems are homologated on the network, and why can residential subscribers choose from 40+ modems but business customers have 4-5 choices?", and "who can I talk to about getting my modem approved for connection?" I'm still waiting for a response.
Yeah, they can pay lip service and say how terribly sorry they are for the poor treatment I've gotten... even as they continue it. These are not complicated questions. Getting answers shouldn't be a 3 month odyssey. And why is my modem not a threat on the residential service, but is on the business service? Does the business service have inadequate security? And we pay more for this?
Update 5: Weeks later and no follow up. They can write "we'll follow up", but they don't actually do it, do they?

Wonderful people to work with
Wonderful people to work with, Pete Lara. Polite, knowledgeable and an all around great "people" person. Installation went smoothly and we were set up and going in no time. The installer, I believe his name was Joe (from El Campo) was super helpful. Looking forward to good days ahead. Thank you all.
