I used to have multiple domains and 3 hosting accounts with 123--small to fairly large active sites.

Increasing downtime, email interruptions, and out of control spam in the past 1-2 years + more serious hosting for business needs made me move to another host.

Good points:

Cheap. Lots of server control compared to other hosts, especially more expensive ones which are very controlling and limit what you get. Downside to this freedom is idiots can abuse and misuse it. You basically get a lot for very low prices and are left to it. Good if you know what you are doing and the server you are on is decent and not overloaded.

In the past, every quarter or so services, bandwidth and storage was increased radically for free on my 123 accounts.

Recently it has been like pulling teeth to get them to release my domains.

123 customer support is not bad. It's not very professional in approach--very casual, simple emails back and forth--but they always got the job done, did not hide behind bureaucracy or try to hook me into new fees. I can't say the same for mid-level or top of the line hosts I've used.

All things considered, this is a cheap host that seems increasingly unreliable. If you are not experienced with cpanel and site management, this may not be the place for you to learn unless you can do that well on your own.
