Screen Shot 2019 03 15 at 2.29.41 PMFounded in 2000, Nucleus is a Belgium-based company offering a unique “uptime-as-a-service” package. The website’s available in English and Dutch.

Features and Ease of Use

Nucleus offers a range of hosting services including cloud hosting and managed hosting. To give you an idea, its plans come with the following core features:

  • Domain registration available
  • Choice of Linux or Windows operating system
  • Free SSL certificates
  • Up to 10000MB disk space
  • Unlimited data traffic per month

Nucleus has its servers co-located in multiple Tier III Belgian data centers. That should mean you get less than 1.6 hours of downtime per year. The company is ISO 27001:2013 certificated for data security and has clear corporate social responsibility guidelines.

It’s quite interesting; the company is clearly extremely passionate about its uptime (there’s even a dedicated service called “uptime-as-a-service”), however I wasn’t able to access the SLA page on the website. I followed up with support, who sent me its uptime SLA document. Unfortunately, the uptime guarantee for shared hosting is “best effort”.

When you are choosing a shared hosting plan, you have the option to choose between Windows or Linux as your operating system. The plans support ASP .NET (versions 1.1, 2, 3.5, 4) and PHP (versions 5 through 7) respectively, along with all the regular databases e.g., MySQL and Microsoft SQL.

If you’re a beginner, the situation is less clear. The plans do support the standard CMS programs like Drupal, Joomla!, and WordPress, but neither a one-click installer nor a website building tool are clearly advertised on the website.

Pricing and Support

Given the level of value-added features is not particularly high and the resource quotas are low, the prices do seem expensive. Having said that, this is a Belgian company, so the local prices are higher than similar companies around the world.

When you checkout, it becomes apparent that you need to purchase an annual plan. There’s no option to buy a month-to-month plan at all, which is pretty restrictive. There also isn’t a money-back guarantee, so you really are making a big investment when you start.

If you want to contact the team, you are limited to an online contact form from what is easily accessible. The site also states that there is support via phone and email, but that information seems harder to locate. There’s a large knowledge base with tons of useful documents, however, ideally, I’d like to see more ways to get in touch.

I contacted the team mid-afternoon on a weekday via the online contact form. I wanted to get more information about the uptime SLA. I was pleased to receive a detailed response within one business day.
