Site has moved and propagation of DNS looks pretty complete, but sometimes local caching, your ISP’s own DNS or other things may be getting in the way.
Various potential fixes - please Google if you need instructions- my iPad is the only device still seeing the old site for now and I find posting links etc. tiresome on it!
Dump browser cache (with Safari you’ll need to enable the Develop menu - why they put it there is beyond me)
Restart browser
Restart computer
Flush DNS cache in terminal
If that doesn’t work, change your DNS settings in Network settings to use Google DNS, at least temporarily. Network->advances
DNS->change to 8.8.8.8 and on the second line, 8.8.4.4, then apply. Pretty much guaranteed to work.
See you on the new hosting!!
