Attached is typical pings I get through Spectrum in my area. The delay/issue is seen as internal to Spectrum and thus there is nothing I can do. Is this typical?
Users need to understand that the ONLY performance guarantee that Spectrum provides is that the data transfer speeds in both directions will be at least 80% of their speed tier levels. There's no way for the user to control the network routing or exit location. The exit point when using a VPN is selected using the address of the VPN server site instead of the address of the actual target. Spectrum has less than ten exit sites across the entire continental USA on their transport network that interface to IXP router locations.
This has nothing to do with a guarantee, it has to do with usability. If the service is not usable, then guarantee or not, I can't use it. There is a serious bottleneck. Since the bottleneck is in Spectrum's control, I think it would be in their best interest to improve it. Right now, I have to look at alternatives but was hoping to provide constructive feedback to try and help improve this.
If you can identify the IP address of the specific hardware that is failing or causing what you believe is a bottleneck, Spectrum can guide a maintenance tech to that segment of their transport network. Including the device name, if it is available, would be a good cross-check for them.
Unfortunately the graphic you inserted into your posting is not of high enough resolution to be decipherable by forum readers. That's one of the limitations of Spectrum's text-based social media platform.
I'm viewing the forum on a laptop LCD with full 1920 x 1080 HD resolution, but the graphic isn't anywhere near that good, looks much closer to an ancient CGA . So pardon me if I misread any digits in the IPs.
Nearest device with long delays is Spectrum 18.104.22.168 The device name field suggests that it is nominally located somewhere near Lincoln, Nebraska.
Second site with long delays is t-core at 108.170. 209.228., one of the IXP contract carriers in the Chicago area. That one is beyond the edge of Spectrum's transport, not under their control, and is probably causing big internet connection problems for lots of people.
