Yunwei123 (yunwei123.com) has focused exclusively on server operations and maintenance since 2006. We do not build websites, run promotions, or engage in any business unrelated to your servers.
We prefer to be “the person you can reach when things go wrong.”
Our Journey
In 2006, Yunwei123 Studio was founded, starting with just one server and a few clients. At that time, mature cloud hosting and O&M services were not yet available in China. Many website owners had no choice but to rely solely on “contacting customer support” when their VPS broke down.
The experience accumulated over these years evolved into our current methodology:
- Early on, we frequently helped clients deal with hacked sites and DDoS attacks, gradually forming a complete process from forensics and cleanup to patching entry points;
- We handled numerous WordPress sites for foreign trade clients, migrating them from shared hosting to VPSs and then to dedicated servers, giving us a clear understanding of “which architecture suits which business”;
- The issues we helped clients resolve most often were not sudden failures, but problems that “gradually deteriorated” — such as stopped updates, failed backups, and unmonitored systems. These issues don’t cause immediate outages, but once they accumulate to a certain point, they fail all at once.
Therefore, our service focus is not on “fixing” but on “preventing it from breaking again.”
What We Do and Don’t Do
What We Do
Cloud server management, host management, WordPress foreign trade site management, website management, annual/monthly website maintenance plans, SSL certificate ordering and configuration, and AI program development and maintenance. This also includes related migration, security hardening, and incident resolution.
What We Don’t Do
Website building and brand design, SEO content and backlinks, cloud resource holding and payment on behalf of clients, and account operation management. We do not accept these tasks because they require different teams or involve financial and entity qualification risks.
We list what we don’t do upfront because one indicator of reliability is whether a company accepts every type of job.
How We Work
Inspect Before Acting
Always understand the current state before making any changes: system version, service dependencies, scheduled tasks, and external dependencies. Maintenance that skips this step usually reveals itself half a later as “we don’t know when it broke.”
Backup Before Modifying
Even actions like malware cleanup are destructive. Leave a recoverable backup before any change, and verify that it actually works.
Change One Variable at a Time
If you change three things at once and the problem disappears, you won’t know which change fixed it. This is why we avoid the “try everything” approach.
Keep Records
Who changed what, when, why, and how to roll back. Delivery documentation and change logs are standard, not extra services.
Define Boundaries
We clearly state what we cannot do. For tasks that are possible but require extra effort, we explain the cost clearly. We make no vague promises and never downplay difficulty to close a deal.
Explain Root Causes
After resolving an incident, we don’t just say “it’s fixed.” We explain why it failed, why there was no alert, and how to prevent recurrence.
