Start: 2026-10-15T10:00:00+00:00 We are currently carrying out urgent maintenance on all of our core routers. The routers are being serviced one after another. During this work, network redundancy is reduced globally. We do not expect any service interruptions, but you may experience increased latency. This maintenance ensures the long-term security and stability of our infrastructure. We appreciate your understanding and thank you for your patience. We are still in the process of performing this maintenance. Thank you for your patience. In_progress2026-11-06T15:36:38+00:00
Start: 2026-11-09T06:00:00+00:00 Estimated end: 2026-11-11T15:00:00+00:00 During this time, technicians will be upgrading various power supply components, including the UPS system in NBG1-DC2 . The work should not negatively affect our server systems. You can see which data center your server is located in by doing a trace route (for example, by using https://dnstools.ws/).
Start: 2026-10-28T17:08:08+00:00 A critical security vulnerability has recently been identified in the EDK II UEFI firmware component (CVE-2026-97631, CVSS 9.5). Further details can be found in the advisory: https://github.com/tianocore/edk2/security/advisories/GHSA-99cj-7hg9-mp4m What is affected? The vulnerability affects systems that boot over the network using PXE. During the boot process, an attacker may be able to execute malicious code through specially crafted network packets, even before the operating system and its security mechanisms (e.g., Secure Boot) are active. Systems that are already running are not directly at risk; the vulnerability can only be exploited during a PXE boot. An official patch is not yet available. What do we recommend? As an immediate precautionary measure, we recommend avoiding reboots of your hosts until further notice if they use PXE boot. What happens next? We are currently analyzing the impact on our environment and developing further recommendations and additional protective measures. We will inform you promptly as soon as new findings or updates become available. Network filters have already been in place for cloud servers for some time. These protective measures are now fully implemented across our Cloud infrastructure, resolving the issue for Cloud. For dedicated (bare-metal) servers, we are continuing to explore ways to further expand these protective measures within our data center networks. The network filters described in our last update are now active at our network edge and between our locations. We are completing the rollout of the filters on cloud servers today. For dedicated (BareMetal) servers, we are currently evaluating how to extend these protective measures further within our DC networks. Until then, our previous recommendations still apply, especially for dedicated servers: Please avoid reboots where possible, and if a reboot is necessary, temporarily block incoming ICMP packets using the Hetzner Firewall.

Start: 2026-06-26T06:00:00+00:00 Due to the continuing high demand and the limited availability of required hardware components, the provisioning of cloud servers at our locations is currently only possible to a limited extent. Given this situation, we are currently required to restrict the creation of new cloud servers for both new customers and some of our existing customers. The selection of affected existing customers is made at random. Unfortunately, it is not possible to individually influence or prioritize specific requests. We are continuously monitoring the situation and working intensively to expand capacity. More details can be found in this article: https://docs.hetzner.com/cloud/general/faq#why-can-cloud-instances-occasionally-not-be-ordered Thank you very much for your understanding.
Start: 2026-06-12T12:00:00+00:00 As part of our ongoing optimization efforts, we are migrating the compression format of our image archives from tar.gz to tar.zst (zstd) to significantly reduce installation times. The file extension of the archives has changed accordingly. If you are operating an automated installation environment and reusing existing installimage configurations, we kindly ask you to review the respective IMAGE parameter and update the file extension to reflect the new tar.zst format.
Start: 2024-07-05T06:00:00+00:00 Phishing is a serious digital security threat, which causes billions of dollars in damages every year. It’s a risk that both everyday users and companies should not underestimate. There are currently phishing emails circulating in the name of Hetzner. You can recognise these emails by the following features: Sense of urgency: Be careful about any emails with subject lines that ask you to do something urgently, for example, subject likes, “Last reminder: accept the new data protection policies”, “Urgent: renew your domain xyz or it will be locked”, or “Your contract will end soon”. Fake sender: Look out for emails with fake sender names like “HETZNER”, “HetznerSupportTeam”, “Hetzner Online GmbH”. The sender is also fake if the email address does not end with “@hetzner.com”. Links that look real: In the email texts, there are links that look real at first, but that will take you to fake Hetzner login pages. These fake login pages will try to get you to enter your Hetzner login details or your credit card details so they can steal them. If you think an email is fake, do NOT open the email at all. And if you accidentally do open the email, do NOT click on any links. If you get an email like this, delete it immediately. If you already entered your username and/or password on site that you think was fake, you should immediately change your Hetzner password at https://accounts.hetzner.com. To better protect your account against hackers, we strongly recommend that you activate two-factor authentication (2FA) for your Hetzner Account: https://docs.hetzner.com/accounts-panel/accounts/two-factor-authentication/ Please do not call our telephone support about phishing-related issues. Instead, write to us at support@hetzner.com. You can see a collection of phishing emails that we know about here: https://docs.hetzner.com/general/others/phishing-email-collection
