We have updated mirrors.gandi.net following today's announcement of the GHOST vulnerability. This newly-discovered flaw is in the popular glibc library, which is used in many Linux distributions and different flavors of Unix. The newly-discovered flaw, which has been present since November 2000, enables an attacker to execute code remotely on a vulnerable system.

We recommend that you upgrade your servers immediately. The following patches have already been made available by the distribution teams:

We will keep this list and our mirrors up-to-date as more affected distributions release their fixes.

If you are a Simple Hosting customer, we recommend that you restart your instance.


The year 2015 is coming and it's bringing a slew of changes with it. One of those changes affects the way VAT tax is applied on "electronic services" (such as a domain name) purchased by European residents.

Simply put: people living within the European Union must pay for these electronic services (i.e. "nonmaterial goods", more info on this is linked to further down on the page) no longer with the TVA of the country where the merchant is located (practically speaking, from where the services were purchased), but rather, the VAT of the country of residence (country where the service was consumed). The territorial rules pertaining to purchases made by European organization which have an intra community VAT number (mainly companies) remain unchanged.

Since Gandi sells electronic services, all of our products (except t-shirts) will be affected by this change.

 

To give you a concrete example, take the VAT rates of a few EU countries:

  • France: 20%
  • Spain: 16%
  • Denmark: 25%

If a French customer buys a domain that costs €10 from a company located in Spain, he or she will pay €12 (€10 + 20% French VAT). A Danish customer buying the same domain from the same Spanish company would pay €12.50 (€10 + 25% Danish VAT). And finally, a Spanish customer would pay €11.60 (€10 + 16% Spanish VAT).

Note that this measure only affects so-called "Telecommunications, broadcasting & other online services", as defined by the VAT Directive. Therefore, actual physical goods sold via "distance selling" (clothing, etc) over the Internet are not affected by this change.

Note also that the sale of electronic services to persons who reside in a non-European Union country will not be subject to European VAT (export), even if these countries are geographically European (ex. Switzerland).

For more information on the different VAT rates in Europe, see this PDF or this website.

 

Some examples of electronic services concerned by this are:

  • Providing and hosting of websites, remote maintenance of programs and hardware,
  • Providing of software and their updates,
  • Providing of images, information and texts, and databases,
  • Providing of music, films, videogames and online gambling, as well as political, cultural, artistic, sports, scientific, or entertainment programs,
  • Providing of online educational services.

Did you know?
If you bought or transferred a domain to Gandi in the past year, you were automatically given a promo code you can use for a discount of 50% off of the purchase of an annual instance of Simple Hosting, our easy and powerful hosting solution. 
And that's not all!
Who buys anything sight unseen, even at half-price? Before you commit to Simple Hosting for a whole year, you'll probably want to test it out.
 Well, there's nothing easier. Just:
  •      Go to the Simple Hosting instance creation page,
  •      Select the programming language, size and database you want
  •      If it isn't already the default, select the "10 free test days" duration option 
  •      Complete the instance creation form and confirm the instance creation
The instance you create will be available for 10 days. If you want to keep it longer, you can use the coupon! Get 50% off for one year, or renew it for the shorter interval option you want (at full price).
 
Pro tip: if you renew before the end of the 10 day trial, the next time interval still starts at the end of the 10 days. No trimming!
 
We try to make it simple (otherwise we wouldn't call it Simple Hosting!). Part of that is making it free for 10 days :)

We are pleased to announce a new version of the statistics tools for Gandi Simple Hosting and Cloud VPS servers.

You can now see detailed usage stats on your instances and servers, enabling more advanced performance analysis. This feature makes it easy to see at a glance that you need to increase or decrease instance size, RAM, or CPU amounts, or use Gandiflex to do so automatically, allowing you to optimize the behavior of your applications in the cloud.

 

Network throughput visualization

These new statistics tools are already available on your instance or server administration page or via our API. The new statistics tools are still in active development (please see notes below), and we're eager to hear your feedback and ideas at feedback@gandi.net.

Accessing stats via the admin interface:

Check the "Statistics" tab of your Simple Hosting page or VPS admin page. We have added new visualizations that allow you to see several types of information:

  • Processor use (CPU)
  • Network utilization and throughput
  • Free and used disk space (on Simple Hosting) or Disk I/O (on VPS Servers)
  • RAM used (on Simple Hosting only)

You can filter the data by instances/servers, date, and even periodicity of visualization (e.g. by hour, day, or week).

Accessing stats via the Gandi API

A new method has been added to the Gandi API to allow you to integrate performance data into your scripts and applications, or to import it into another tool for monitoring or automated alerts, according to your needs.

Just call the method api.hosting.metric.query, passing your API key and the details of the request as arguments, as explained in the API documentation.

Notes

If you aren't seeing any network usage data, you may need to stop and start your Servers for data collection to start.

We will soon start displaying maximum usage values (95th percentile), instead of average usage values, for the selected time period.

Getting help

We hope you find this to be a useful tool. More information is available on our support wiki (instance stats | server stats) and, as always, our support teams are here to help.


This December, we will be making a change to make Simple Hosting easier to use, as well as more manageable.

Currently, there are three separate signatures, one for each datacenter, for the SFTP protocol you use to transfer files to Gandi Simple Hosting instances.

In a few days, we will replace We have replaced these keys so that they are all the same (and thus easier to manage). The new key will have the following signature, whether your instance is hosted in our Paris, Baltimore, or Luxembourg datacenter:

2048 35:e0:5a:a9:54:12:55:6b:ce:41:8c:c1:9e:35:1d:f6 (RSA)
1024 80:c7:a8:05:dc:79:92:f1:9c:b7:61:46:a7:ad:2d:f7 (DSA)

For reference, the outdated key signatures were as follows:

Paris (sftp.dc0.gpaas.net):

2048 02:15:f6:35:d7:01:3c:58:74:8c:e4:0e:96:61:35:6f (RSA)
1024 36:c2:9c:5c:5b:d0:7e:5b:78:e4:ee:47:ad:aa:1c:8e (DSA)

Baltimore (sftp.dc1.gpaas.net):

2048 f8:ed:00:17:1a:88:9f:4d:15:fb:84:46:1e:19:4f:c5 (RSA)
1024 69:84:9b:dd:3b:cd:9a:20:df:60:60:e0:6d:cd:5e:e7 (DSA)

Luxembourg (sftp.dc2.gpaas.net):

2048 c1:0b:b5:1d:57:cb:00:75:22:a5:6b:d3:bc:73:64:5a (RSA)
1024 7c:ac:f0:23:6b:d6:e8:78:67:4c:72:95:9b:14:61:eb (DSA)

How does this affect me?

In most cases, all you need to do is accept the new key when you log into your instance via SFTP. The client will prompt you the first time you use it to connect after we make the change.

If your client doesn't handle the changed signatures gracefully, you can manually flush the key on the command line (replace dc0 in the command below, if necessary: dc0 = Paris datacenter, dc1 = Baltimore, dc2 = Luxembourg):

$ ssh-keygen -R sftp.dc0.gpaas.net

and then use your sFTP tool and reconnect again and accept the new foreign key.

If you have any questions or concerns about this, let our support team know. We are here to help!


On Tuesday, 7 October, we experienced a series of serious incidents affecting some of the storage units in our Parisian datacenter. These incidents caused two interruptions in service for some of our customers, affecting both Simple Hosting instances and IaaS servers.

The combined effect of these interruptions represents the most serious hosting outage we've had in three years.

First and foremost, we want to apologize. We understand how disruptive this was for many of you, and we want to make it right.

In accordance with our Service Level Agreement, we will be issuing compensation to those whose services were unavailable.

Here's what happened:

On Tuesday, October 7, shortly before 8:00 p.m. Paris time (11:00 a.m. PDT), a storage unit in our Parisian datacenter housing a part of the disks of our IaaS servers and Simple Hosting instances became unresponsive.

At 8:00 p.m., after ruling out the most likely causes, we made the decision to switch to the backup equipment.

At 9:00 p.m., after one hour of importing data, the operation was interrupted, leading to a lengthy investigation that resulted in eventually falling back to the original storage unit. Our team, having determined the culprit to be the caching equipment, proceeded to change the disk of the write journal.

At 2:00 a.m., the storage unit whose disk had been replaced was rebooted.

Between 3:00 and 5:30 a.m., the recovery from a 6-hour outage caused a heavy overload, both on the network level and on the storage unit itself. The storage unit became unresponsive, and we were forced to restart the VMs in waves.

At 8:30 a.m., all the VMs and instances were once again functional, with a few exceptions which were handled manually.

We inspected our other storage units that were using the same model of disk, replacing one of them as a precaution.

At 12:30 p.m., we began investigating some slight misbehavior exhibited by the storage unit whose drive we had replaced as a precaution.

At 3:50 p.m., three virtual disks and a dozen VMs became unresponsive. We investigated and identified the cause, and proceeded to update the storage unit while our engineers worked on the fix.

Unfortunately, this update caused an unexpected automatic reboot, causing another interruption for the other Simple Hosting instances and IaaS servers on that storage unit.

By 4:15 p.m., all Simple Hosting instances were functional again, but there were problems remounting IaaS disks. By 5:30 p.m., 80% of the disks were accessible again, with the rest following by 5:45 p.m.

This latter incident lasted about two hours (4:00 to 6:00 p.m.). During this time, all hosting operations (creating, starting, or stopping servers) were queued.

Due to the large number of queued operations, it took until 7:30 p.m. for all of them to complete.

These incidents have seriously impacted the quality of our service, and for this we are truly sorry. We have already begun taking steps to minimize the consequences of such incidents in the future, and are working on tools to more accurately predict the risk of such hardware failures.

We are also working on a customer-facing tool for incident tracking which will be announced in the coming days. 

Thank you for using Gandi, and please accept our sincere apologies. If you have any questions, please do not hesitate to contact us.

The Gandi team
