Past Incidents

22nd May 2024

FRA3 Several Hosts down

One of our VM nodes in FRA3 is down, this affects the following U7 hosts:

  • farbauti.uberspace.de
  • europa.uberspace.de
  • eurydome.uberspace.de
  • bernardi.uberspace.de

we are investigating the problem

  • All U7 hosts are up and running again

  • 21st May 2024

    FRA3 network connectivity in FRA3 impacted

    A core router is unexpectedly rebooting. Connectivity should be restored soon.

  • Core router reboot finished. Connectivity is restored.

  • 14th May 2024

    FRA4 network outage

    We noticed a network outage at our FRA4 datacentre. Based on information of our provider, this is reportedly caused by a power outage at a major data carrier.

  • Our datacenter has immediately switched to backup connections, but it took a few minutes until the routing tables have been adapted accordingly. During this time, we observed partial connectivity in varying ways (some peerings worked faster than others). The majority of connections was back on 12:06 GMT+2, three minutes after the incident. A few peerings needed up to ten more minutes to reconnect cleanly. Between 12:21 GMT+2 and 12:23 GMT+2 there was another short outage due to works needed to stabilize the situation, which resolved quickly.

    ferdinand.uberspace.de Zeitweilige Performance Einschränkungen bei ferdinand.uberspace.de

    Aktuell kann es auf dem Host ferdinand zu einer Einschränkung der Performance kommen. Dort läuft aktuell eine Kampagne von postmitherz.org über die wir uns sehr freuen, die aber teilweise zu hohen Lastspitzen führt. Wir haben für den Host daher bereits einen eigenen Server Node freigemacht um für den Zeitraum (bis 18.12.) der Kampagne möglichst viel Spielraum zu geben.

    Solltest du dennoch ein Problem mit deiner Seite feststellen, schreib bitte unserem Support und wir suchen gemeinsam nach einer Lösung.

  • Die Aktion ist beendet und es sind keine weiteren Einschränkungen zu erwarten.

    FRA3 Partial downtime/failures FRA3

    we observe partial failures on fr3

  • Everything is up and running, and the last host is also showing normal performance again.

    The root cause was likely an unintentionally installed package on the Ceph nodes during an OS update, which caused the IPs in Ceph to become disoriented.

  • All hosts are reachable again, and their services are running. However, we still observe high load on some of them. We are addressing this issue, but overall, the situation has already significantly eased.

  • After a network/configuration problem of our ceph-cluster at FRA3, we have the situation under control again, but still have some follow-up errors to fix. some hosts and services are still down. We are working on it

  • Hardware down

    We have received down notifications for the hosts neujmin howell callirrhoe eirene bernardi epimetheus and chaldene from monitoring, suspect underlying hardware as the cause and are currently investigating the incident.

    We are in process of rebooting the crashed hosts right now.

  • Our upstream provider changed the routing, it looks like this fixed the issue. If you still experience IPv6 timeouts, please contact us at hallo@uberspace.de.

  • 26th October 2023

    Hardware down

    The hosts eukelade, ijiraq, reinmuth, alnilam, kojima, euanthe are down because the underlying piece of hardware crashed. We are rebooting it on a different one.

    25th September 2023

    FRA3 IPv4 connectivity impacted

    We observe that IPv4 connectivity is currently impacted. IPv6 connectivity is unaffected.

  • After an unexpected core router reboot, the standby router took over. While in theory both routers have exactly the same routing configuration, we discovered a bug in the IPv4 routing configuration which only affected the standby router. This bug is now fixed and IPv4 connectivity fully restored since 14:08 CEST.

    Today from 15:30 (GMT+2) we will be doing maintenance works on our routers and uplink connections in our FRA4 datacenter (95.143.172.0/24 network), after some instabilities observed in the past which we now want to put to an end my making some major changes. The maintenance works will be carried out in person in the datacenter and in collaboration with the datacenter provider. While we try our best to limit impact on the connectivity, there might be shorter periods of network outages.

  • All network config and router upgrades have been finished successfully.

  • 25th July 2023

    multiple host are unreachable

    Multiple host are currently unreachable, we are investigating.

    A full list will follow ASAP.

  • The underlying issue was a switch config problem causing the Ceph storage network to be unresponsive, so no disk I/O was possible for the - still running - U7 VMs. The problem has been solved for now and according to our service monitoring, all VMs with all of their services are running fine again.

  • All host seem to be operational again.

  • All host - except crater.uberspace.de - are reachable again. Some might still need time to recover before normal operation.
