Leland Vandervort — Fri, 13 Nov 2009 16:12:00 +0100

We will be performing a major network maintenance operation during the night of 19 to 20 November in order to further improve our infrastructure.

This maintenance will commence on 20 November at 01:00 AM CET and finish at 07:00 AM CET.

During this time, three connectivity outages are expected, each lasting approximately one hour and will impact most Gandi services.

All hosting operations will be suspended throughout the maintenance period.

We apologise in advance for any inconvenience caused.

Network Maintenance 28-30 October 2009 (Completed)

Leland Vandervort — Thu, 22 Oct 2009 16:30:00 +0200

We will be performing major upgrades to our network distribution infrastructure during the nights of 28 to 30 October. (This is the maintenance rescheduled from 21-23 October) During this time Gandi services will experience a number of intermittent disruptions in connectivity beginning at 1am (CEST) with maintenance activities finishing by 7am (CEST) each day. We will, nevertheless, endeavour to minimise impact to services where possible, but given the scale of the upgrades being performed, most services will encounter at least some disruption. Gandi Hosting will be the most affected during this operation, with an expected cumulative total of approximately 90 minutes of network outage. Other Gandi services will be partially affected.

We apologise in advance for any inconvenience this work may cause.

UPDATE 2009-10-30 05:20 CET: This work has now been completed and brings additional capacity, resilience and performance to the distribution layers of the network. We will be scheduling a further maintenance in the coming weeks to further enhance the features of the new hardware that has been installed. We will of course keep customers informed nearer the time.

Incident on Air Conditioning in Datacentres - Resolved

Leland Vandervort — Wed, 19 Aug 2009 23:29:00 +0200

As a result of a problem with the air conditioning in two of our datacentre locations, we have had to halt all services in that location. This impacts pretty much a quarter of our hosting and all sitemaker services as well as one of our DNS clusters. We are working with our colocation partners to attempt to restart the services as quickly as possible.

We will keep you informed of developments on this issue.

We apologise for any inconvenience.

23:40: Our colocation partner is currently migrating to a backup cooling system.

00:40: The temperature is slowly dropping, and we will being by reactivating part of the services. Our colocation partner is still working on repairing the cooling system, however, but we do not yet have an estimated time to repair.

07:00: We are now staring to bring services back up in the second datacentre affected by the cooling system failure. Some services still degraded, however.

07:45: Most services are now available.

08:15: Incident has been resolved. Any customers still experiencing problems with their servers, please contact support via the online form.
