Recovered from Disaster!


This week we had a true test of our disaster recovery

procedures.  At 11am on Monday, water

started pouring out of our comms room ceiling! 

True disaster!  Luckily the deluge

narrowly missed our server racks but started to pool under the floor and didn’t

take long to start spreading across the room. 

I instantly started to shut down servers, most critical first, and then

had to cut power to the entire floor via the main breaker.  The water kept coming for 2 hours, the floor

was soaked with pools of water underneath the raised floor.  We waited to access the extent of the damage

and potential downtime and decided that it didn’t warrant switching to our

offshore site—within 4 hours of the flooding we had relocated servers providing

essential services to another part of the building, re-routed the internet

links and had all vital services running. 

A professional flood recovery team was called in, the source of the

water was found to be a faulty toilet overflow which had been leaking for weeks;

this was pooling underneath the ground floor until it finally found a way to

break down in to the basement!  The water

was pumped out, industrial fans and dehumidifiers were set-up and left overnight.  By Tuesday morning the room was dry, we

removed each server and checked for any signs of water or condensation, luckily

none were found.  By Tuesday lunchtime,

within 24 hours of the incident—services were back up and running as usual.

We were very lucky that the water didn’t come down directly

above our racks, this would have been a true disaster.  Thankfully the fact that we shutdown all services

and then cut power to the floor as quickly as possible meant we suffered no

hardware damage or data loss.  Phew!

It just goes to show that disasters do happen, so make sure you have plans in place which you have tried and tested.
