Lag and downtime
I am disappointed with their servers as they keep on shutting down for some kind of maintenance and upgrades. This downtime is disturbing and needs to be taken care of asap.
Quick and reliable support
I had some questions about setting up my website and domain, sent an email and got a response within 5 minutes with detailed instructions which helped me sort things out.
I've used SPD Hosting for about a year now and have found them to be an excellent solution for my own hosting requirements. My site has never gone down.
