A store was targeted in a layer 7 DDOS attack which resulted in random timeouts and 502 errors while our servers were scaling to match the rapidly increasing load. This partial outage affected 6% of total requests for 2-3 minutes.

After scaling up we were able to handle the load and there was no need to cut-off the network to the targeted shop. The attack lasted for 1 hour and we kept monitoring the load and were ready to blackhole the traffic in case it would affect other shops.
