It happened at GlobalSwitch Clichy, near Paris. From what I gathered from a french forum[1], it started with a flood and then a fire. No rooms have been affected, apparently.
Cooling pump failure lead to water leaking into the UPS room. Batteries caught fire and firefighters can't access the room. Fire is contained although.
It is the Clichy's one. It's not that dug into, where did you get that from? (Used to work there circa 2010). I think the water retention made its way to the battery rooms. No recent floods (nor rain) in Paris (nor most of france) lately.
