Charter (Spectrum) has notified us they’re going to try maintenance again Thu 6 Dec 2018 12:00 AM – Fri 7 Dec 2018 6:00 AM with a claimed 240 minutes loss of service during this timeframe.
Since the previous attempt went extremely poorly and resulted in 57 hours loss of service, we can only hope their maintenance group is prepared for this second attempt. We will provide updates as necessary.
UPDATE 12/6/2018: Charter (Spectrum) tried to migrate our circuit again, and now IPv6 is broken due to BGP failing to establish.
UPDATE: Charter (Spectrum) IPv6 BGP was finally restored on December 10 at 22:01.
