Few notices about Moscow, M9-IX, and last outage

1) M9 have UPS power for a few days. BUT - it is 60V DC power. Only a very few routers or switches are able to use it. 2) Power outages in Moscow data centers are very rare event, because most have 2 - 3 different power inputs. 24 May failure was caused mainly by operator's error, who reconnected power system back after few transformers broke, and caused chained failure. 3) As a result of this (I never saw power failure in Relcom data center for 15 years of working there), generators are not common there. 4) M9-IX is not the only entrance to Moscow, but it was the main entrance. As I know, few other entrance nodes was not affected.
