The use of the internet in the first half of 2020 literally exploded, putting pressure on the web and many DNS have contributed to congestion.
Despite the fact that the Unlock has been going on for some time, the impact on the network continues to be felt strongly.
Phase 2, still characterised by a strong component of the workforce in smart working, puts under strain the network infrastructure. The result is a decrease in performance on both the fixed and mobile networks.
First of all, it is necessary to understand whether the Internet connection is objectively slower than normal. To measure the download speed of the connection, you can use free websites like SpeedTest.net.
If the speed shown by the online test is much lower than expected, then it is appropriate to perform the speed test on another device. If the result were similar, the problem would not depend on the device.
Otherwise, the problem would be confined to a specific device. It will therefore be worth evaluating the integrity of the operating system, with the tools to detect and resolve problems, verifying the presence of viruses or malware.
In addition, many factors affect the performance of the internet in a specific context. For example, the strength and quality of the WiFi signal. In a home environment, it is advisable to check that other users are not generating abnormal volumes of web traffic.
Analogous control will be done on your computer: you happen to have open file sharing applications, responsible for bandwidth saturation.
The benefits of DNS for web browsing
A very important but not very well known advice concerns the DNS server. The DNS signature stands for Domain Name System, and it is the system that regulates the translation of network nodes names into IP addresses.
By default, devices use your Internet service provider’s DNS servers. Although they are reliable servers, they cannot always count on the power of a global player like Google. Google’s DNS are among the best in the world, and deliver performance at the top of the market. Moreover, it is worth remembering, the use is completely free.
DNS can be modified in two ways: directly from the router, if the model you own allows it (several ISPs unfortunately do not foresee it) or in the settings of fixed and mobile devices.
Among the advantages offered by DNS as strong as Google’s, we remember greater performance and lower latency (which translates, for example, in faster opening of web pages). Better security, given the solidity of the networks and protocols used. And finally, no less important, privacy is protected: Google says that it periodically deletes data on the activity of the browsers connected and not to associate it absolutely with other data that could identify users.
