RE: Apple "Private Relay" VPN

Slight tweak - it's not all devices, just those owned by people who are paying for an iCloud+ plan. Probably the majority of Apple users do pay for some kind of iCloud+ plan, but that's pure speculation on my part with no real data to back it up. But yes, it can cause interesting issues. :) -- ...

RE: Cable TV

We never put traditional coax cable TV into our residence halls with the exception of the graduate housing halls and common areas in the undergraduate dorms. When I was an undergraduate back in the 90's, cable TV was one of the most often requested upgrades to the dorms, but our president at the time ...

We have a policy on network extensions: https://www.it.northwestern.edu/about/policies/extensions.html In practice, we follow much the same pathways that others have outlined - we'll work with departments to see what the actual need/use case is. We might install our own managed switch, we might allow ...

We have been long time Infoblox customers (indeed their offices used to be down the street from us in Evanston!). It's definitely not cheap, but it has been working well for us for many years. Support has been good, but we also have not had to use it very often. Our department is responsible for the ...

Typically there's also cable TV service in those houses, so there's also cable modem internet service as well. What we do is set up a separate "house" SSID that bridges to the cable modem internet. We also provide eduroam access as well, but the house SSID has a traditional PSK that the home and IOT ...

RE: Internet Comms Campaign - release unused phone lines

Found In Egroup: Communications Infrastructure and Applications \ view thread
So with respect to actually shedding phone lines and numbers, one item that comes up in discussions every now and then is one of institutional identity and what role an institution-issued phone number.line actually plays there. I'd suspect that many places have some kind of policy saying that you need ...

We are not yet pulling the trigger on any migration away from our on-prem telephone system, but in preparation for moving to something new, we are embarking on a project this year to reclaim "dormant" phones, which we are defining for the moment as any hardware telephone that hasn't participated in an ...

We've not worked with that company, but we're in discussions with some others. Key concerns are likely going to be surrounding privacy and data handling (anonymization/de-identification of MAC addresses/IP addresses, who has access to the raw data, etc etc). The other main approach to this question ...

Traditionally for football games we've had 2 field technicians on site to deal with immediate telecom/network issues during home football games. We do not provide that level of support for any other athletics events. For some basketball games in our newer arena, Athletics contracts with a 3rd party vendor ...

RE: Staffing ratios for network engineers

Found In Egroup: Network Management \ view thread
I'd definitely fall into the "it depends" camp. :) I don't think things can be distilled down to a single simple ratio of engineers to network devices, because there's a ton of variability there outside of the raw number of devices (assuming we could agree on what to include in the device count, what ...

Heh. Looks like this last came up on the old mailing list back in 2021. We'll see if this platform allows the old forwarded email thread to get through. Based on this conversation back then it jogged my memory to verify with our finance folks that we had gotten the appropriate exemptions filed with ...

RE: Common Area phones for safety/emergency

We don't rely on common area phones as emergency phones. If an emergency phone is desired/needed/required in an area, then we install a dedicated emergency phone. For us, a common area phone is a different use case, more along the lines of what you refer to as convenience or shared applications. We have ...

I've been a member of the various EDUCAUSE lists/groups for longer than I remember.

I certainly learned a giant pile of stuff from everyone here, and I have been struck ...

As can be imagined, there were no firm disclosures made to talk about the futures of any specific products/services, since the acquisition is still moving toward completion in late 2024 or early 2025. The general statements that I got from sessions that I attended were nothing surprising at this point ...

RE: Do you use private or public CA to sign your RADIUS EAP certificate?

Found In Egroup: Wireless Local Area Networking \ view thread
We've been using public CA for EAP-PEAP since we first started doing 802.1X authentication back in the 2000's. Obviously as time has gone on, that has proven to be suboptimal for a number of reasons, including the need to rotate the certificate at ever-decreasing intervals, not to mention the security ...
