There is a very high possibility that changing your web host now could actually save you a lot of grief in near future. In past people have hardly paid attention to their web hosts and have thus been ignorant to fact that this is a choice that makes a huge impact on performance and ultimately success of any online venture.
1)Security at your web host matters The security settings of your web host matter. They actually matter a lot. So much so that security of your site from hacks and all other increasing online dangers depends on it. An intensive review of your web host may lead you to look at a few other web hosts and their infrastructure with intention of moving your hosting elsewhere.
2)Ddos attacks on another site in your hosts network will affect you The danger of Ddos attacks is on rise. Ddos or Distributed Denial-of-service attacks have been targeted at various well known sites in past costing losses.
These are attacks where massive false online traffic is generated towards your site, thus crippling it. The attack is executed when thousands of compromised zombie hosts are directed against a target. These zombie hosts are unwittingly recruited from millions of unprotected computers online and are quickly build up waiting for command to launch a Ddos attack. The symptoms are that a site receives impossibly high false traffic that literally shuts it down.
The protection from this menace does not come cheap. The most recent Cisco Ddos protection appliance costs about $200,000. What this means is that many web hosts will not have this protection. And what makes it worse is that attack does not need to be targeted against you for you to be affected. An attack on any single site a particular hosts' network will affect everybody.
