I have recently migrated this blog and two other domains to the Vultr VPS Hosting (Get $20, 4 Months Free VPS). It is not an easy decision as QuickHostUK is still a good choice among the traditional VPS providers.
QuickHostUK VPS Outage
Two days ago, the Quickhostuk VPS had an outage: The SSH connections were unstable, slow and unresponsive. The htop command show the CPU/Memory usage was low but the server was just very slow.
The issue was with the master hypervisor my VPS is running on. It became overloaded and CPU / Disk IO was too high. QuickhostUK had to reboot it to bring it back into service. While it is rebooting it must boot all of the VPS which can take around 10 minutes.
The outcome of this accident was 2 hours of downtime and when it is back. A MySQL table is crashed but I was able to fix it by logging into the MySQL Console and run the command Repair Table wp_options which is to repair the WordPress table wp_options table.
QuickHostUK says “We do have battery backed cache on the hardware to allow data to write from the SSD to your VPS, but if you VPS is unable to function correctly for any reason then yes, data corruption could occur. For this reason please do consider your backup options whether with us or another provider or even simple daily MySQL dumps.”
Is QuickHostUK Overselling their VPS?
“Not overselling, but yes same principle. There are many VPS on 1 hardware server. And usually they can all run perfectly fine. However, if all VPS suddenly need max CPU at the same time then it can cause load on the hardware CPU to provide clock cycles to the virtual servers. For this reason there are limits in place on each virtual server for CPU cores, CPU time % and CPU weight. It was discovered some older VPS from legacy systems had no such limits applied so they were able to use more CPU that was fair. This has now been corrected and the current load is well within operation limits and all services are showing healthy.”

The Advantage of QuickHostUK Traditional VPS Hosting
QuickhostUK Support is Fast. You raise a ticket and they will get back to you very soon, in my case, no more than 1 hour. They are very kind, helpful and supportive.
As a traditional VPS company, QuickHostUK offers competitive price than the CloudVPS. I roughly pay 33 GBP for 6 cores, 3GB RAM, 5TB Transfer and 50GB SSD. With CloudVPS, this specs generally means a lot more expensive, not to mention paying for a dedicated server.
The Disadvantages of QuickHostUK Traditional VPS Hosting
As a traditional VPS company, QuickHostUK is no different. It means that if the hyper server is down, all the VPS on it are down. The scalability is limited compared to Cloud VPS. The stability is also worse than the Cloud VPS where the hardware can generally self heal. e.g. one machine down, the cloud system will quickly migrate the VPS so it is not affected.
Cloud VPS Nodes are Faster
As the CPU/RAM for Cloud VPS is isolated, generally the Node is a lot faster for Cloud VPS compared to the same specs in traditional VPS. In this post, I did some benchmarking using PHP and it is worth mentioning that the Vultr VPS is a lot faster even it is only a single core with 768 MB RAM, compared to the QuickHostUK 6-core, 3GB RAM VPS. The CPU main frequency is 2.4GHz and the only single core is used because the PHP script is not multithreading.
Pay monthly/annually v.s. Pay by usage
For traditional VPS hosting, you normally pay monthly or annually (usually get a month discount). For Cloud VPS, you can pay as you go, which is usually billed hourly. That means that if you don’t need it, you stop the VPS instance and then also stop paying for it.
VPS Recommendations
Vultr is clearly a better choice. Vultr has offered Cloud VPS Hostings over 15 global locations.
However, QuickHostUK is also a good choice if you want a pure UK server. They offer competitive VPS hosting as well as dedicate servers.
What is a Cloud? The short and easy-to-understand definition
Cloud is a large redundant network system that each node (VPS) has a quite isolated CPU, RAM and HDD/SSD resources. The redundancy makes it more stable so that when hardware fails, it does not affect the node and the cloud can self heals it quickly. The Cloud is also more scale-able so you can ask for (upgrade to) more resources later, if you want to.
