Hi MrTM. Again, welcome.
One of my colleague was having his site on Stablehost europe host cp09.eu . Because he was not having RVsite builder when his site was on cp09.eu; when he requested for it, they have moved him to eu01 server.
This is understandable. It costs the host extra licensing fees on every server where it's used. However, site builders in general are falling out of favor -- due to WordPress, Drupal, etc -- so hosts are reducing their costs by only providing it on a couple of machines. And any client that needs it is simply placed on that server. So that's the reasoning, if you were curious.
Does this have any effect on performance
The number of domains is not always a useful number for ascertaining resource use.
For example, this site (digitalFAQ.com) eats up most of a dedicated server by itself -- a non-budget server at EuroVPS
. There's almost nothing else here. The domain is actually spread into a slave VPS (via sub-domain), for some of the work we're currently doing with video developers (software engineers creating some amazing things); all long-term projects, nothing to show for a little while. So a single domain can take two servers.
, however, I have probably 10 sites. One of those "sites" is a single page, and the domain is mostly used for sending personal email. Two more are small portfolios (one HTML, one WordPress). One site does get modest traffic, yet within the confines of what shared hosting is good for. My use at Stablehost represents the average user. And the average user does not impact the server much at all.
Given the quality of hardware used by Stablehost, the restrictive (hard-to-abuse) CloudLinux OS, and the LiteSpeed webserver, it's not easy to cause performance issues on their servers. Beyond that, they managed their systems quite well, so anything that gets by the hardware/software is handled by human intervention. It's possible that one of these servers could handle 1,000 domains without issue. The owner of Stablehost is actually pretty honest about their customer saturation, so they can give you a direct measurement, if you ask. Third-party tools (like yougetsignal.com) are often just guessing. At one point, the saturation points were written in the Stablehost public knowledge base, with more details on the hardware specs for the servers. They would not fill up systems beyond 50-60% of available resources, if I remember correctly.
Most of the domains on that yougetsignal.com list are parked, meaning 0% resources are used.
including a an adult site.
The LiteSpeed license does not allow for adult sites. If you see one, report it to Stablehost, as they'll have to remove it due to licensing agreements.
On the other hand, you may be on an Apache server, where it would be allowable. In this case, it's something to be aware of, yes. Porn can cause one type of "bad neighborhood" effect, but only after a certain saturation point and with certain kinds of content filtering (as used by edu, gov and corporate sectors). Pornographic sites are all over the Internet, and found in pretty much every datacenter and IP block. It's difficult to be in a porn-free zone, and most IP-based filtering is dodgy. Malware and phishing sites, along with "SEO" linkfarm scams, are far more devastating to the bad neighborhood effect as considered by search engines. Porn is not malicious or trying to cheat/game the system.
Does this have any effect on
search engine ranking
Search engines don't pay much attention to IP addresses; it's not a primary ranking vector in their algorithms. This is the main reason SEO hosting is a myth
and does not work. Companies like Google, Bing and Baidu know that shared hosts (technically known as "virtual hosts") exist, and are quite common. Dozens, hundreds or even thousands of sites can co-exist on a single IPv4 address, and the owners of those sites might not even know each other. Furthermore, due to the community nature of some demographics (bloggers), interlinking is both potential and expected. So if links within an IP don't affect rank, simply co-existing on an IP certainly won't.
Search engines are more affected by how quickly your site loads. Stablehost is providing excellent servers, so any slowness tends to be with clients using overloaded blogs or forums with too many plugins. WordPress has far too many badly-written plugins, such as the "All In One SEO" plugin that can cripple even a dedicated server. Ideally, you want to use as few plugins as possible -- no more than 10 max, with none of them being heavy.
Does this have any effect on
It should not, no. HTTPD (web) and SMTP (mail) are not really related for the purpose of "spam". The only reason the IP would be listed as spam is if somebody starts to sending spam from one of those domains.
You can always monitor the DNSBL/RBL status.
- Either manually check your IP at http://www.dnsbl.info
- Or sign up for free alerts at http://www.rblmon.com
Can he ask them for again change in server back to cp09.eu? If so, what reason he should quote in his ticket to move it back?
He could move back, but he may lose the RVSiteBuilder. I don't see any major or valid reason of concern here. It's good that you and your friend are mindful of these things, but upon further inspection, I'm not seeing any reason to move back.
I am sorry if I am seeking more from forums like this.
Not a problem. Helping others is why we put this forum online 8 years ago.
