3. Network fault self-diagnosis guide
When encountering network connection problems, it is recommended to follow the following steps to troubleshoot:
1.basic check: Confirm that the router indicator light is normal, the network cable connection is stable, and the device network settings are correct.
2.Multi-device testing: Try to connect multiple devices such as mobile phones and computers to the same network to confirm whether it is a single device problem.
3.Operator status query: Learn about local network conditions through the operator's official website or customer service.
4.Network diagnostic tools: Use ping, tracert and other commands to detect network connectivity.
5.DNS test: Try changing the DNS server address, such as using 8.8.8.8 (Google DNS) or 114.114.114.114.
4. In-depth analysis of recent hot Internet events
1.Cloud service provider DNS failure: On November 1, an abnormality occurred in the DNS system of a large cloud service provider, causing websites using its services to be unable to resolve domain names. The incident lasted about 2 hours and affected multiple industries such as e-commerce and online education.
2.International fiber optic cable outage: On November 3, a major submarine optical cable in the Asia-Pacific region failed, causing a significant increase in network delays in China, Europe and the United States, and affecting the business of some multinational companies.
3.Impact of 5G network upgrade: In some areas, 4G network resources have been occupied due to 5G network upgrades, and users have reported that 4G network speeds have dropped significantly.
