We will be performing major network upgrades to our backbone network in Paris during the night of 23-24 March 2013.
The purpose of this work is to replace our current (aging) backbone network routers with newer generation equipment allowing for increased capacity, performance and resilience. During this time, all Gandi services in Paris will experience brief periods of network unavailability and/or instability as the migration proceeds.
This activity will not impact the individual Gandi services themselves, but rather only the network connectivity between the internet and those services. As a result, there will be no need for hosting customers to restart their IaaS or PaaS servers/instances. Services in our Baltimore datacentre will not be directly affected by this maintenance, but some periods of routing instability and reconvergence may be experienced, though these will be far less prevalent than for the Paris services.
This migration will commence at 01:30 CET (00:30 GMT) on Sunday 24 March 2013, and we estimate between 10 and 15 minutes of major network outage during the initial migration, followed by a number of brief periods of network instability during the remainder of the migration. The entire migration activity should last approximately 90 minutes, but no more than two hours.
Operations will be ended at 05:00 AM CET (04:00 AM GMT).
We apologise in advance for any inconvenience this may cause.
Due to a fibre cut between Telehouse2 and Equinix in Paris, some Gandi services are disrupted. We are attempting to mitigate as much as possible, but some services are dependent on this inter-site connectivity. Our fibre suppliers are working to resolve the issue as soon as possible.
14:00 CET (13:00 GMT): Connectivity has been restored.
We have lost contact with our infrastructure at Telehouse1 (Jeuneurs) in Paris as of 03:11 CET (02:11 GMT). Our technicians are en-route to investigate the problem.
Affected Gandi services are:
1/3 of the DNS systems, whois for domain registry, and mail redirection service.
We will update here as we obtain more details.
UPDATE: 04:01 CET (03:01 GMT) - our core router at Telehouse1 had suffered a system crash resulting in the outage of this site. Our engineer successfully restarted the router and we have obtained crash dump information from the router for analysis. All services are once again operational.
Due to a technical issue, DNS zone updates are not being processed since midday. Our technical teams are investigating the cause of the problem and are working to resolve the issue as soon as possible.
Update: 14:00 CET : The problem has been resolved.
