Is Vaultas AS53480 still a live network? I don't see any prefixes associated with the ASN, and haven't seen any traffic across MICE since May 30th, 2017 from the ASN. I think the prefixes that were advertised from this ASN are now advertised by Compudyne AS47096, maybe that's a clue. There web site seems live. Is Monticello Fibernet AS393466 still a live network? I don't see any prefixes associated with the ASN, and haven't seen any traffic across MICE since March 20th, 2017 from the ASN. I don't see the prefixes previously associated with this ASN anywhere on the Internet. Their website seems live, but says "delivered by Arvig" now, maybe that's a clue. :) Is Introvex Solutions AS135886 still a live network? I don't see any prefixes associated with the ASN, and haven't ever seen any traffic across MICE from the ASN. I don't see the prefixes previously associated with this ASN anywhere on the Internet. Cloudflare says their website is offline, maybe that's a clue. Just want to clean things up if they are gone.
