In the weekend (1st-2nd September 2018), we'll replace the boxes that provide you with Internet connectivity. You will experience temporary connectivity outages (could take an hour or two), both on Wi-Fi and Ethernet.
13th and 14th corridor will suffer as well, though less than the corridors below.
Dejvická dormitory will also be switched over, which will turn it off for less than 20 minutes.
Thanks for your understanding!
