Measured on this block in Apr-Jun 2026 — the ceiling the hotel's WiFi sits under. Shared WiFi, captive portals and per-device caps only make it slower, never faster.

Fixed line vs mobile
| Network | Down | Up | Ping |
|---|---|---|---|
| Fixed broadband — what the WiFi runs on | 32.3 | 14.3 | 21 |
| Mobile — your own SIM | 66.6 | 27.0 | — |
Your SIM may beat the WiFi. Mobile upload here (27.0 Mbps) tests higher than the fixed line — worth trying both before you rearrange your day around the room WiFi.

Outages in Czech Republic
| Started | Ended | Network | Cause |
|---|---|---|---|
| 21 Sep 2026, 06:30 UTC | 21 Sep 2026, 08:15 UTC | O2-CZECH-REPUBLIC | technical problem |
Country- and ISP-level outages, not hotel-level. A national outage takes the hotel with it; the hotel's own router failing will never show here.

Where this listing came from
OpenStreetMap has no record of this place, so its name and location came from Overture. The speed figures above are Ookla open data for the surrounding tiles and do not come from Overture.
