Our european data center provider (VNET a.s.) had experienced outages from 06:40 to 08:10 UTC+0.

All services are now fully operational.

We were not yet provided with any reason.
We apologize for any inconvenience. Thank you for your understanding.

So you would like to switch to us? And you do not know how? We hear you and you are not alone.

That is why we are introducing free web site and e-mail migration to us.

We will transfer ALL your emails and web sites to us at no charge. All migration work is done usually during weekends or when you have the lowest traffic.

Web site and e-mail migration is done by our qualified professionals. Web sites are migrated by PHP developers.

Now there is nothing to keep your web site from a better home. Just contact us and we will do it for you. Some of our new customers get part of their money back from their old web hosting providers.

Is there a downtime?

No, usually we do it without downtime.

How do we transfer emails?

Just send us a table of emails with passwords. If you do not know the passwords we will need the root access to your VPS.

We can do it without loosing or returning single e-mail and no downtime.

How do we transfer web sites?

Actual web developer will be transferring your web site. We will make all the necessary adjustments in the code of your web site, like changing database settings etc.

In case of transferring the entire VPS or dedicated server, we can even guarantee data consistency.  For example if you have busy eshop and you do not want to loose orders made on old server during the migration we can redirect all traffic at HTTP ports from your old server to new one. Your data will be consistent in exchange for small downtime.

 

Search engines are constantly grading each and every web site on the internet. Usually it is a number between 0 and 10, the higher the better. The more people link to your web site, the better, because the grade of your web site goes up.

However when people started to create more web sites just to link them together, search engines stared to ignore some back links. For example if one web site is linking to another and they share the same IP address, the backlink just does not count.

This is where SEO hosting or multiple IP hosting comes to rescue. You assign different IP to each of your web site and search engines will consider backlinks as legitimate. Remember, IPs should be on different IP ranges (blocks) as it so on our pay as you go web hosting.

For best results, you should register your domains using different names, or use privacy registration on some of your domains. This way, search engines will have no way of finding a connection between your sites.

Our web hosting offers three IPs for each web server and there are multiple web servers per datacenter and multiple data centers around the world to choose from. It means if you web host with us, you will gain access to many IPs. All this from one account and for free.

 

 

 

 

In the ideal world, when you write something on your storage device (HDD, SSD…), you should be able to read the exact same data later. But in reality it is not true and as our storage devices grow in size, the data corruption problem is getting bigger too. Data gets corrupted all the time, sometimes you will even not notice it.

Bit rot – silent data curruption

Silent data corruption is when a one or more bits on HDD flip their state. Disk manufactures of course know about it and price their HDDs according a rate, this happens – URE (Unrecoverable Read Error) or UBER (Unrecoverable Bit Error Rate). According to the data from manufacturers if you have three 4TB drives, you can be sure at least one bit was flipped. The European Center for Nuclear Research (CERN) published a paper in 2008 and they found approximately 38,000 files were corrupted in the 15,000TB of data they generated.

So bit rot happens more often than you think. Were you listening to your favorite MP3 and then suddenly CHIRP! ? Your MP3 file was corrupted. If you think one bit will not make a difference, look at this example image with one bit flip:

Even if all HDDs would be 100% reliable as data storage, data would be silently corrupted by RAID cards, loose cabling, controller bugs, DMA parity errors, power supply problems and so on.

You might think buying the most expensive HW will fix this, but it will just reduce the amount of data being corrupted.

A better solution: End to end data protection

End-to-end data protection requires each data block to be verified against an checksum on the filesystem level. If the checksum does not match, the filesystem then needs to:

1. read the data from different copy (in case of mirror RAID) or calculate it from stripe drive (RAID 5)
2. fix the corrupted data on the fly

But almost no file systems are actually doing this. This means data gets corrupted daily and users are just wondering what is wrong with their files.

In order for this to work filesystem needs to communicate directly with your storage device without any ‘middle men’ like RAID card, LVM, partitions, external storage etc.

Web hosting

Is it important for web hosting? Of course yes. Maybe it happened to you that your web site has stopped working and after re-uploading the same file everything was OK. This could be just one rotten bit.

Why take the chances in data corruption lottery when you do not have to? Use hosting provider that offers end to end data protection web hosting.
