Greenhost sponsors the Time is Now Foundation

The Time is Now Foundation is a lobby group for sustainability. The foundation states that it is about time we start to invest time and money in introducing sustainability to Dutch high school kids. With teaching sustainability on high schools the foundation aims to create an ethical change.

To achieve this, the foundation organises round-table events quarterly. During these events a think tank is created to identify barriers and solutions for integrating sustainability in the secondary education.

Greenhost thinks it is important that more people are properly educated about sustainability...

Improving Privacy DNS

Last week, a small Greenhost-delegation visited the Internet Freedom Festival in order to meet other people active in the field of Privacy and Internet Freedom, and get new ideas to improve upon our services. Inspired by a great session by Daniel Khan Gillmor we immediately set up a new DNS-over-TLS server, allowing advanced users to use the internet more privately.

The Domain Name System (DNS) underpins most of our use of the Internet, by providing a way to look up IP addresses from domain names. By design, it provides very little privacy. While more and more sites use encryption once the...

Bepakt (Dutch for 'packed') is an informational site about zero-waste shops in Europe. Zero-waste means reducing waste dumping to zero, by designing and managing product chains in smart ways. On bepakt.com you can find hundreds of addresses of shops that sell packaging-free products.

In the rest of this blog post we will look at the reason for this abuse, how you can see if you are contributing to this problem too and how you can prevent it.

Unwanted email sent from hosting packages

Recently we've been getting more complaints (via Feedback loops) about unwanted emails being sent from the web hosting packages of our customers. We always look into these complaints seriously.

Making Greenhost even greener

Since Greenhost was founded we have made as many "green" choices as possible. We started by working together with EvoSwitch, continued by buying second hand furniture and developed a shared hosting environment that is extra energy efficient. But at Greenhost we do not only want to be greener than the other companies. We want to be as sustainable a company as we can be!

That is why we have created a permanent team of employees that will dedicate themselves to keep the "Green" in "Greenhost. We have identified the following as important next steps:

  • Yearly reporting of our energy usage

Reason for Outage 12 February 2018

What follows is a relatively detailed and technical description of the reasons for the outage. Because we understand not everyone wants or understands this much detail we added a simpler and shorter summary of the problem:

There was a problem with the devices (switches) that regulate the (redundant) internet (network) connections to our data centre. In trying to solve this isolated problem unfortunately a feedback loop occurred that clogged the multiple connections.

We have multiple connections going to the data centre to prevent losing access to our machines, however this issue managed to...

From now on you can't send any unidentified e-mails from a non-existing email address

To meet the standards we did a necessary update on our SMTP mail server on the 21th of December. This means that from now on you can't send any unidentified emails from a non existing email address. The exceptions to this are the following types of addresses: webmaster@…, noreply@…, no-reply@…, wordpress@…, cron@…, and root@….

Do you still want to use a non existing e-mail address you can simply add a wildcard/catch-all email address. When that is set, all the emails to addresses on this specific domain will be accepted and email can be sent from all possible addresses.
