We will be upgrading the RAM on supremecenter16.co.uk, which would result in a 30 minutes downtime. The time window for the upgrade is between 2 AM BST and 3AM BST (3AM CEST – 4AM CEST).



While the technicians at the data center are upgrading the RAM on the server, all services will be off-line, including web sites, e-mails and control panel access. The downtime should not exceed more than 30 minutes. The RAM upgrade will improve the performance of the server.



We apologize for any inconvenience caused. Thank you for your understanding.

No one likes to wait for a web page to load – if a site is taking too long to load, the visitor is more likely to close it and move on. This is especially true for blogs, which are meant to be seen and read. Today, we will share with you several tips on how you can speed up a blog running on WordPress.

1. Eliminate unnecessary plugins

Don’t use too many plugins – they will noticeably slow down your website. Imagine them as too many apps running at the same time – they will affect the overall performance of the blog. Keep the number of the plugins low – let’s say from 5 to 10, but don’t go over 20.

2. Optimize your Database

All the information for your blog posts and comments is stored in a database. So, to speed up the loading speed, you can optimize this database. There are two ways to do that – with the WP-Optimize plugin, or manually. The plugin is the easier way, but always remember point 1 of this article. If you want to do things manually, follow these instructions:

1. Inside your web hosting Control Panel, locate and open PHPMyAdmin- you can find it in the Database Manager section.

2. Once logged in the PHPMyAdmin, select your database.

3. Click “Check All” at the bottom of the page.

4. Choose “Optimize table” in the drop-down list next to it.

5. Done!

3. Cache your Database

Another way to speed up the work of your database is to cache it. This way, you will reduce the number of queries made to the database each time a user visits your blog. You can cache your database with the DB Cache Reloaded plugin.

4. Disable Post Revisions

Post Revisions exist since WordPress 2.6 and they are useful when there are several writers working on the same blog, or if you make constant changes to your blog posts. If left enabled, this feature will create multiple entries for a blog post in your database, effectively slowing it down.

5. Use a Cache Plugin

You can also create static versions of the most visited web pages. This way, you will reduce the queries made to the database. And static HTML pages load much faster. There are a lot of cache plugins, but be careful with their configuration – if they are left untended and not properly configured, they tend to use too much CPU power.

6. Optimize your images

Have your images optimized – you can use Photoshop’s “Save for Web” function, which will save the image with a good balance between size and quality. Here is a list of other image optimization tools:

Online Tools:

• PunyPNG
• Smush.it
• Online Image Optimizer

Desktop Tools:

• Shrink O’Matic
• PNGGauntlet

7. Optimize your CSS and JavaScript files

Another way to speed up your website is to optimize the CSS and JavaScript files – this way you will reduce the size of the files and save some disk space and decrease the server load. There are several tools you can use to do that.

To compress the CSS files, you can use several tools:

• WP CSS plugin
• CSS Optimizer
• CSS Compressor

To optimize your JavaScript files, use:

• JavaScript Compressor

Dear Customer,

We are writing to give you some information on the service interruptions some of you may have experienced lately. For the past 17 hours, our Australian server – supremecenter300.com, has been undergoing an urgent maintenance due to a major outage of an important international backbone.

The main reason for the extensive downtime is an incidental problem with the server RAID configuration, which is now being sorted out.

We would like to assure you that our administrators are working round the clock to resolve the issue and get the server back online as soon as possible.
We are in constant communication with the Data Center staff and have been informed this issue will be resolved within 10-12 hours.

We apologize for any inconvenience caused by this totally unpredictable event, and the disruption of service to our customers accounts on this server. As soon as we have further information about this issue we will update you. Thank you for your understanding regarding this matter.

Today we replaced one of our core network switches in the US Data Center (Peer1 – Fremont, CA). The switch was completed with just 30 seconds of downtime. The results are very good – about 3 to 5 times increase in speed compared to the old network switch. Now even customers from Europe can download with several megabytes per second from our US network in Peer1.

Today our network had a downtime of about 20 minutes, caused by a faulty core network switch. We have replaced the network switch and now the network is back to its normal condition.
