alexhost is currently unstable
I have about 6 vps in alexhost and all of them are unstable as of last few days.
Even their main website is unstable. Sometimes it loads, sometimes it doesn't.
Depending from where you access you may not feel it but if you have visitors/clients accessing from different regions of the world it will be unstable.
Their network is very unstable and slow. Sometimes traceroute can't reach their servers.
Hope it returns to normal.
