I wanted to open this link but got this instead:
'This request is blocked by the SonicWALL Gateway Geo IP Service.
Country Name: Slovenia.
Initiator IP: 89.143.109.255'
Don't remember of getting such treatment before.
This says that the hardware/software firewall called Sonicwall has blocked access to that site. It is Probably used by your local internet provider (or company portal) and configured with a filter on names, key words or known IP addresses of "bad" sites. I see that Dell as well as others, including manufacturer (SonicGuard.com ) sell these. The IP address that it displays is for IzydorSymanski-net in Lublin, Slovenia (You?). I would guess that this is either a new hardware firewall or an existing one has had an update to it's list of allowed/blocked access sites.
