Stuttering/halting playback both in the browser and in the Windows desktop app

I am using Deezer from Central Europe (Hungary), and in the past few days encountered issues with playback numerous times. The song simply stops for a few seconds or even minutes, likely because it cannot download the next chunk from the server. This theory is supported by the fact that downloading a song has also become significantly slower (once downloaded though, the songs play normally). Seeking into the song helps sometimes, but then it gets stuck again a minute or two later.

Please take a look at the servers serving this area because something seems to be amiss.

EDIT: I’d like to note that all other sites and apps work perfectly, so my own Internet connection is not the issue.
