Recently my client and I both lost our email services on a phurix host. It was reported to normal support and through their 'urgent' support route but their response was nothing, not even an acknowledgement. 10 days later and
... More many emails from us and still no response.
I was on the basic personal option but my client was on small business level option and loss of emails was a serious issue for them so we had no choice but to move to another host. I changed our MX records to point to the new host and got our email functionality back instantly, then I redirect our nameservers. This issue was not the only time we've had poor support so moving hosts had already been discussed; this was the final straw though.
The new host is fastcomet.com and actually worked out cheaper than phurix as we're combining our domains onto the one host, but price is not the main concern, it's the support and so far it has been very good from fastcomet, with a support ticket and online chat options available - something that phurix used to have but dispensed with several years ago unfortunately.
Also their claimed 100% reliability is only on the network connectivity - it doesn't include server downtime!
There may be a solid reason for their total lack of support but as we don't know what this is we didn't have much choice; they've hosted several domains for me for over 10 years but loyalty only goes so far, bye bye phurix. Less
