Stalling MySQL under DDoS

In the most recent DDoS attack on my serversĀ I’ve noticed that my provider was blocking all malicious pockets, but was causing the network latency big enough for MySQL connections to time out.

After increasing the connection time and net read timeout limits the problem was gone.

connect_timeout=30
net_read_timeout=45

The pages seem sluggish, but they do open up within 5-7 seconds.
