What does this mean?
A DoS attack is an intentional malicious action that is designed to temporarily disable a service. We have systems in place that respond to common attacks for our clients, filtering them for durations that are chosen based on the likelihood of false positives and the level of damage typically caused by the specific attack.
Depending on the size and characteristics of the attack, and the nature of your software, you may or may not have seen effects from the attack before it was filtered.
Most attacks are spoofed (use random fake IPs). This means that it is usually not possible to examine the traffic and determine the attacker. We will likely not be able to provide further information on this attack.

Obviously, this is from 4/22, but it may be ongoing.
GIven that information, I think the server did quite well to be under attack. Hopefully, the attack slows down for now.
