I am a siteground customer..
Professionals: Steer clear of their shared hosting..
Here's why..
Their database PHP file isn't big enough to power fantomaster database.. So, if you plan on cloaking and using fantomaster, don't go with siteground because they won't let you touch the php buffer size.
Also, they put caps on cpu cyles.. There's only so much CPU processing you can execute on those shared 9.95 accounts, even though they call it unlimited.. That's bullshit. Even if you're running simple little wordpress scripts, don't plan on running more than 2-3k hits per day PER ACCOUNT without going over your cpu limit.
Also, there's an addon slot fee around $30 if you plan on adding multiple domains to the same account + the cost of the new domain.
So how do you get the special and be ok? When your service expires (addon slots do EXPIRE after a year) You've got to pay the ridiculous renewal costs for plain 'ole 'decent' shared hosting..
Upload speeds (publishing to server) during the day are f*cking horrible. Sometimes it's as slow as 1.5/kilobytes per second. They are much better at night around 2:00am CST..
I recommend that consumers take advantage of this deal if they want a cheap reliable domain and they are just starting out.
Remember folks.. "You get whatcha pay for."
I can't speak for their dedicated servers as I am not a customer of their dedicated plans; just being honest with my experience..
