So, I woke up this morning to an email from our main host, who owns the server all of our public gameservers run off of. It turns out that last night, someone we've (most likely) banned from the server decided to launch a DDoS attack on us. Unfortunately for them.. It was very weak. As a result, it ended up not affecting anything at all.
Our host has kindly launched an investigation into this for us, I'm sure I'll hear from them again when they find out some more information on the attack. However, I've decided to post the details of the attack below, for transparency's sake. Click through to the post to see the full list. I've put a graph at the bottom as well.
Had we been hosting servers from someone's home, this would probably have crippled the servers. Let this serve as a note to anyone here that may try to host their own servers at home - don't, host with a professional hosting company instead.
