I hope someone contacted you off-list because their NOC's answer was unacceptable. Pretty sure it's a human error and not malicious but network operators have to react quickly to this type of issue. Several days? Even several hours is a ridiculous response time. Contact their upstream providers and mention they (the upstream) are not doing their job by filtering their customer's BGP announcements. Contact IXes (if they're connected to any), peers, etc. Rinse and repeat. At last, threaten them with legal actions by sending angry emails or calls to senior ops/management/marketing/legal department.

We are down. Have been told it will be several days until restoration. And frontier is advertising our ips so I can't even advertise them out a different route. The NOC had been completely unhelpful. 570-707-3000 mhoppes@rivervalleyinternet.net
