Has anyone else had terrible internet speeds since Vonovia switched to SYNVIA?
We are tracking significant service disruptions affecting the European hosting landscape. Below is an essential update regarding the ongoing instability at Hosting.de and Webland, alongside a request for community intelligence regarding Vonovia’s ISP subsidiary, SYNVIA media GmbH.
Hosting.de: Root Cause Analysis and Remediation
Following the severe service degradation on November 27, 2025, Hosting.de has released a technical post-mortem. The disruption began at 1:30 PM CET, affecting the provider’s core network infrastructure. This failure rendered client systems intermittently accessible or completely unavailable.
Technical Diagnosis
The engineering team identified the failure point within the primary core switch stack, which utilizes a Juniper Virtual Chassis configuration.
- The Trigger: High load peaks caused synchronization errors between chassis members.
- The Result: Extensive packet loss led to immediate service interruptions.
- Failed Redundancy: A prepared fallback to a replacement Juniper stack failed as the redundant hardware exhibited identical load synchronization faults.
Stabilization Strategy
Acknowledging that the Juniper architecture could not guarantee stability, technicians initiated an emergency migration overnight. They shifted traffic to a parallel core switch stack from an alternative manufacturer. While this unauthorized migration required manual configuration adjustments—causing extended latency during the night—it successfully restored stability by the morning of November 28, 2025.
Current Status
Operations are currently stable. However, the engineering team is finalizing post-migration verification. Clients should anticipate minor, brief interruptions as the provider completes the fine-tuning of this new core environment.
Webland: Ongoing Crisis in Switzerland
The situation for Swiss clients utilizing Webland remains critical. Service disruptions began on November 24, 2025, and have yet to be fully resolved. Data indicates this total outage impacts approximately 75,000 domain owners.
While Hosting.de has stabilized, Webland’s recovery trajectory appears slower. Status reports from December 5, 2025, confirm that mail server protocols remain compromised. Swiss IT outlets suggest these technical hurdles may persist throughout December 2025. Businesses relying on Webland for mission-critical email infrastructure should consider implementing temporary redundancy measures immediately.
Community Intelligence Request: SYNVIA media GmbH
We are investigating the service quality of SYNVIA media GmbH, the subsidiary ISP for Vonovia (formerly Deutsche Wohnen).
Tenants currently receive internet and television services via cable or fiber optics through SYNVIA, which has replaced Vodafone as the primary network operator. A disparity exists between our reader reports and public sentiment:
- Reader Feedback: Reports of significant connectivity issues and poor technical support.
- Public Sentiment: High ratings on Google Reviews, which contradicts direct user feedback.
We require verified user data to assess this provider accurately. If you are a tenant serviced by SYNVIA media GmbH, please report your experience regarding bandwidth stability and customer service responsiveness.
