xSF moved to a new IP:

In the context of our growth the past months and the overcrowding of our previous server, we decided to expand our capital by moving to a much stronger server.

The new server is located in France, you will not experience any higher or lower ping. However, your ping will be more stable and synchronization will heavily be increased because this server has a seven to eight times faster internet speed.

New server IP:

samp.xsfserver.com:7777 might also work for you, it is already updated but it might take up to a day to work (DNS).

For the tech geeks, specifications:
Intel Xeon E3-1231v3
16GB DDR3 RAM 1600 MHz
SoftRaid 2TB
500 Mbps bandwith
