西门子 - 历史记录

Sites are back online. Due to the nature of the outage, we are closely monitoring availability and performance.

We do not know when the issue will be resolved on AWS side. We are in direct contact with AWS to get information from them as early as possible, but this is a global outage of yet unknown complexity.

The number of affected AWS services increased further. You can follow their updates here: https://health.aws.amazon.com/health/status

What's Happening

All website services are currently unavailable due to an AWS infrastructure outage affecting the us-east-1 region.

Impact:

• All pages and content inaccessible

• URL redirects not working

• User authentication failing

Cause

AWS is experiencing an outage affecting multiple core services including AWS Security Token Service. This prevents our request processing infrastructure from functioning.

What We're Doing

We are monitoring AWS's service health dashboard. Our systems will automatically recover once AWS resolves the outage.

Expected Resolution

Waiting for AWS to restore affected services. We will provide updates every 30 minutes.

We apologize for the inconvenience. This is an AWS infrastructure issue beyond our control.

This is a wide spread AWS outage. A large number of services that we are depending on are affected.

Status: Resolved
Duration: September 15, 2025 - 15:32 to 16:24 UTC (52 minutes)
Impact: 0.74% of website traffic affected

What Happened

Our website experienced intermittent slowdowns and service errors due to a performance issue with our analytics tracking system.

Root Cause

Analytics tracking calls were blocking the main website response, causing delays when the analytics service experienced issues.

Resolution

We optimized our system to process analytics tracking independently from website responses, ensuring external service issues can no longer impact site performance.

Prevention

This architectural improvement ensures similar analytics service issues will not affect website availability in the future.

Current Issue

We are currently experiencing a major outage affecting www.siemens.com . Users may encounter service unavailable errors or very slow loading times when trying to access our website.

What We're Doing

Our technical team is actively investigating the issue and working on a fix. We have identified the root cause and are implementing a solution.

Next Steps

We expect to have the issue resolved shortly and will provide updates as progress is made.

We apologize for the inconvenience and appreciate your patience.
