I. Clouds in 2026, collapsed a little dense
In the first half of this year, the world's major cloud vendors almost lined up for major accidents. Pick a few representative ones:
- February, Microsoft Azure West: Data center transformer failure, UPS battery lasted only about 6 minutes, control system cascade failure caused the automatic switch from mains to generators not completed, interrupted for about 20 hours. Ironically, Azure's disaster recovery service Site Recovery itself is on the downtime list.
- May, AWS us-east-1: The cooling system couldn't support the thermal load, overheating triggered a power outage, burned out a batch of server hardware, and recovered for more than 28 hours. Coinbase trading was interrupted for nearly 7 hours. AWS itself admitted that the cooling capacity and thermal load were "mismatched"-the power consumption of AI server single rack was 3-10 times that of ten years ago, and the cooling design of the old server room couldn't keep up.
- June, lithium battery fire in New Delhi data center, India: STT GDC/Tata Communications facilities caught fire, server racks and electrical installations burned, Google Cloud local nodes were forced to shut down for nearly three weeks. The worst was tenant Matrix Cellular, an international SIM card company,More than 20 years of operational data may be permanently lost. CEO quote: "It's been 20 days and the backup hasn't been restored. If there was a backup, it would have been restored by now."
- August, Phoenix, USA: Storms cause power fluctuations, chillers fail, room temperatures soar, and customer service is disrupted for about 37 hours by hosting providers such as Liquid Web. Facilities don't even have a public status page, and customers don't know what's going on through several layers of middlemen.
The common thread is clear:This year's big downtime, the root cause is almost entirely physical--Transformers, cooling, batteries, weather, not software bugs. On the other side of the cloud are data centers, reinforced concrete, cables, and chillers, which are afraid of fire, heat, and thunderstorms, just like other human infrastructure.
II. Three direct inspirations for Guangzhou SMEs
Revelation 1: Cloud is an "availability solution", not a "backup solution"
Put data on the cloud, solve the problem of "anytime, anywhere access" and "single server broken data is still there". But the data on the cloud also faces: server room-level disaster (fire above),Your own mishandling(Delete the folder in the cloud disk, empty the recycle bin after 30 days), account theft, arrears downtime, and manufacturer policy changes. Matrix Cellular's 20-year data is stored in the cloud service provider's server room, and it may still return to zero after a fire-because they did not buy backup service levels.
Tata Communications 'statement afterwards was very straightforward:Customers who subscribed to recovery and backup services have recovered, and the rest are waiting.Resilience on the cloud is sold by paid level, not by default.
Revelation 2: AI computing power expansion is crowding out the reliability of traditional infrastructure
The AWS cooling failure was no accident. Industry analysts generally point out that cloud vendors are investing huge amounts of capital in GPUs and AI loads, diluting redundant investments in traditional general purpose computing environments. Forrester even predicts multi-day major cloud outages in 2026. What it means for you: Betting your business systems on a single region in a single big cloud is increasing risk concentration, not decreasing.
Revelation 3: The local "old antique" server is really useful at critical moments
Many of our customers are "cloud + local" hybrid: daily collaboration uses cloud, but core data (drawings, finance, customer data) keep a complete copy on local NAS/server, and then synchronize an encrypted backup to cloud. After the fire in India this year, several customers took the initiative to call and ask how to strengthen local backup-this is a good thing. Local copy is not afraid of cloud room fire, cloud copy is not afraid of office flooding, two legs walk steadily.
III. 3-2-1 backup, the landing version of SMEs
Principle cliché: 3 data, 2 media, 1 remote.
| data type | 1st (working copy) | Copy 2 (local backup) | 3rd (off-site) |
|---|---|---|---|
| Documents/Drawings/Finance | Office PC/NAS | NAS daily backup → removable hard drive (unplug offline storage once a week) | Enterprise Network Disk/OSS Encryption Synchronization |
| Databases (ERP) | server | SQL automatic backup to another disk + weekly full backup download local | Cloud database snapshot or encrypted upload |
| Website/Mini programs | Cloud Virtual Machine | Code Repository (Git) | Database dump is stored off-site once a week |
Three disciplines are more important than the programme itself:
- The one that's offline has to be offline.Remove the backup and put it in the rack. Ransomware crawls along the network, and the backup hanging on the network is equivalent to burial (seeThe ransomware deal.real case).
- Recovery drills are conducted once a month.Pick a file at random, restore it from the backup and open it. There are cases where backup tasks fail silently for three months and no one finds them. We have our own customers.
- The offsite copy needs to be encrypted.Add a password (7-Zip AES-256) to the backup compressed package transmitted to the cloud. Don't put customer information in plain text to a third party.
4. Do you want to "abandon clouds" because of this? No need
To be fair, the annual SLA for cloud availability (99.9%+) is still much higher than the actual level of most SME self-built rooms. These incidents in the first half of this year affected specific services in specific regions, and most users did not feel it all year round. The correct posture is not to abandon the cloud, but:
- Core business: single area, single availability area, streaking, budget enough, multiple availability areas;
- When selecting a cloud vendor, take a look at its status page and historical incident records, as well as-supply chain transparency (whether the accident can be known at the first time);
- Take "cloud one + local one + offline one" as standard, cloud is only one of three.
Data is risky wherever you put it,Put more than two places to be safe. This sentence is worth taking seriously more than ever after the first half of this year.
