Why are we using Softlayer Nameservers?

I was reviewing the live chat transcripts earlier today. An interesting one that was served by “Ronskit”, a live chat operator of Mellowhost caught my attention. One of our visitor was interested to know, why are we using Softlayer nameservers for the domain “mellowhost.com” (http://intodns.com/mellowhost.com) instead of ns1.mellowhost.com or so on. The visitor was more interested in proving that Mellowhost is hosted in a shared server and all of our clients are also using a server that is not really managed by Mellowhost. His excuses were flowing towards why we don’t sell VPS or Master Resellers, or so called “Alpha” Master Resellers instead we only sell Reseller and Shared Hosting. It is eventually hard to answer a management level of query by a sales representative and as expected he wasn’t able to please the visitor 🙂 I quickly thought to write this down for future references.

Experience with Varnish!

When Mellowhost first launched her servers, all of them were using “DSO” module for serving php. I can remember, one of the most commonly used caching plugin was either Eaccelerator or Xcache. Eaccelerator was preferable as cpanel Easyapache have this in their option and can be compiled automatically while rebuilding apache. As time passed, we had to choose suphp instead of dso due to many factors involved. I hope to write them down at later time why we had to move to suphp. But that actually cut the idea of using dynamic cacher in the server. Suphp kills the php process after serving, this allows all the opcode cacher to be valueless. Due to cutting off a dynamic cacher, the server started showing pretty good load average. Although it was a good trade off of IO and CPU usage in cost of security. I was searching for a cacher that would work with suphp in the same technique Litespeed (A paid web server software) does.

wp-supercache plugin for MH servers

I had written about using a cache plugin with all the wordpress blogs in order to reduce the CPU usage before. Although, some of our clients were complaining about issues with the most popular “wp-supercache” plugin with couple of our servers. We use some custom security protection which might block couple of wp-supercache commands. I here therefore, uploaded a workable version of  latest wp-supercache 0.9.9.9 that works perfectly with our servers. You can download the latest version of wp-supercache compatible with our servers here:

Wp-supercache is a property of its original author. More details about this plugin is available here:

48 restless hours!

RAID is not a backup solution, it is proved again! I was planning to write my experience of 48 hours from July 22 7:17 to July 24 7:23 GMT -5, couldn’t really manage to get some time. All the users who were in the Hemonto server should be aware about the recent issue we faced with our RAID. This post is just to elaborate how did we handle the situation.

Some good budget servers!

We use Softlayer and Liquidweb for all of our production servers. None of them is really a budget server provider. Softlayer does sell some budget servers which are not at all good for production servers planned for web hosting services due to their inability to upgrade in future (Like xpress servers). Moreover the price isn’t really right for the same set of hardwares with some other budget provider. We have been using budget servers for our backup servers which usually can hold tons of TBs of data.
