Sometimes it would be 30k pps.
It will follow up saying connections from <ipaddress> is blocked, and the ipaddresses are from all over the world, leading me to believe that it is a DDOS attack.
However, why would that prevent legitimate connections?
1. Is it a DDOS attack? If it is, what can I do to prevent it?
2. Why are some people unable to connect to the server while others are able to?
3. How do I solve this issue?

Well it is a DDOS attack if ipaddresses are coming from different countries that's up to 30k pps (packets per seconds!). The only way you can prevent it is by using a DDoS-protected server, a GRE tunnel service, or a metamod plugin sent above ^.
DDoS attacks works by sending tons of trash packets or query packets (A2S server queries) that are similar to what the CS:GO client sends, which makes it difficult to differentiate between legitimate and counterfeit connections.
Some people are able to connect because their packets are received by the server itself, in the midst of an attack.
