[CentOS-mirror] New CentOS mirror for Sweden

Wed Mar 28 08:35:16 UTC 2018

OK, thanks for confirming. The mirror has now been added.

A traceroute from the university network also shows the packets routed 
directly to Sweden. Despite the .ru in one hostname, it also has 
"netnod" and "sth", which both point to Sweden.

Rascom, a Russian ISP, has presence both in Finland and Sweden, so it 
makes sense for the traffic to be routed to Rascom's network already in 
Finland. Rascom may decide to route their traffic to Sweden through 
Estonia and Latvia, if they have a cable between Latvia and Sweden. 
That's alright, but this was literally the first time in my life I saw 
traffic destined to Sweden routed through Estonia and Latvia so I was a 
bit confused. But times change..
