On September 5, Yahoo Mail faced some of the biggest problems it has gone through lately. Operating problems have affected many users in Romania. Europe was the hardest hit continent. 
UPDATE September 5 12:30 Yahoo Mail still has major issues in Europe. The first complaints were reported on the morning of September 5, around 9:10. Countries such as Romania, the Republic of Moldova, Spain and France have been severely affected.
When updating this article, Yahoo Mail works better in Romania and Eastern Europe. The same cannot be said of Western Europe, where Germany, France (with the Paris region), central Spain and the United Kingdom in London have major problems. At the same time, users in Belgium and Greece say they can't access their email address.
Below is the first original information about Yahoo issues
Even if you say no one uses Yahoo, that's not the case. Yahoo Mail is perhaps the most popular service the company has ever launched. Even though Yahoo no longer exists on its own, but is part of Verizon, the problems still exist and affect millions of users globally.
The platform is unavailable on September 5, at the time of publication of this article. Users from Romania and the Republic of Moldova are affected, as well as from other European countries.
How Big Are Your Yahoo Mail Issues?
The most affected region is Europe. The Down Detector platform, which collects customer complaints when an online service no longer works, shows that the UK, Germany, Romania, Spain and Greece are the hardest hit countries.
Users in Australia, India, but also on the west coast of the United States are also affected by the unavailability of Yahoo Mail.
Most users report having problems with authentication, accessing the site (not loading), but also not being able to read any emails (also because the message is not loading).
As the situation looks at the moment, this is the biggest problem Yahoo has gone through in recent years.
The UK either has a lot of users of Yahoo's mail service, or the servers allocated to that region are totally inefficient. That's where most of the complaints are.
Countries where Yahoo Mail has problems, but which can be used to some extent, include Poland, Belarus, France and Bulgaria. There are not many complaints in Hungary either, while in Germany there are several cities affected.
Since 2017, Yahoo has been at Verizon. Since 2018, Yahoo has also closed Messenger, the most popular online chat service before WhatsApp, Facebook Messenger or other more modern platforms.
