Why are paper LOAs still used?
Why do companies still insist on, or deploy new systems that rely on paper LOA for IP and ASN resources? How can this be considered more trustworthy than RIR based IRR records? And I'm not even talking about old companies, I have a situation right now where a VPS provider I'm using will no longer use IRR and only accepts new paper LOAs. In the year 2024. I don't understand how anyone can go backwards like that. ~Seth

You joined the wrong mailing list then. This is NANOG, which has companies of all sizes and private individuals operating networks. This is not a "global firms" mailing list.

My understanding is that they all get their time directly from the official NIST clocks without GPS or NTP being involved. I used to jump through all the hoops for that but honestly I like the appliances better (they are also PTP grandmaster clocks). I can always disable the GPS inputs if any of the doom and gloom actually comes to pass. ~Seth

This is especially true if the GPS integrates some sort of disciplined oscillator. Note that this is in excess of what NTPd running on a typical OS can reliably retransmit. BUT.. if I was to choose only one protocol, it would be NTP, not GPS, because of all of the reasons you mention. I find it distressing that sites are relying on GPS only. I suspect that this a failure to assign proper risk to using GPS. It's particularly odd when one considers that adding NTP time sources are essentially free and improve robustness and reliability greatly. I liked having a WWVB receiver in my mix, but all the hardware appliances (at least those offering OCXO or Rubidium oscillator options) seem to have rejected it in favor of GPS only. I can only conclude that either vendors think options like WWVB are a dead end or there's no demand for GPS alternatives. Products like the BlueSky GNSS Firewall exist, but not something I've thought was as necessary expenditure for my needs (yet). Mouser lists it at just under $10k. Personally I'm just not that comfortable using random unknown platform and unknown installation conditions time server pools over the big-I internet. I would possibly consider NTP servers operated by entities I have peering with. ~Seth
GGC need portal access restored
I also need someone at GGC to contact me ASAP; a tech showed up on site to replace hardware in a node and I've come to find out my portal access is no longer available and I can't place it into maintenance mode. ~Seth
