Hostkoala down?

It seems none of my sites hosted at hostkoala are working today. And yours?

I got several emails from them over the last 3 days stating that they've migrated my sites to new servers, but I didn't bother checking whether the new DNS works because the sites I'm hosting with them were not a priority for me, so I ignored the emails

Contact them and see what they say

Thanks mate it was the issue you pointed out, they have migrated their servers and their emails were in my spam folder... Thanks again for your help problem solved !
