INC: high latency via various carriers

All ongoing maintenance and cuts have been fixed. All carriers are re-enabled. We consider the situation resolved.

Sparkle has been drained. NTT has been re-enabled to maintain considerable amount of redundancy.

We are currently observing high latency via various carriers (NTT, Sparkle, and Interlink) towards various targets, mostly in Eastern Europe, due to several simultaneous maintenance activities and fiber cuts. We will do our best to reroute traffic accordingly.

Interlink and NTT have been completely drained to mitigate the impact. Further drains may follow.
