Our validator setup complies with Solana security best practices, and our server is protected by various DDOS protection measures provided by our datacenter. In addition, we have a monitoring system in place to notify us within minutes if a server outage has occurred.
Our Solana server is a baremetal server located in a US Ashburn datacenter rented through Latitude.sh. It has an AMD EPYC 7443p cpu with 24 Cores (48 threads) at 2.85 GHz, 256 GB of RAM, 2 x 1.9 TB NVME drives, and 10 Gb/s of bandwidth.
Nope, this is not possible. You remain in full control of your tokens at all times, even if the validator goes offline. This is because the record of your delegated stake lives on the globally distributed blockchain, and not just on any one validator. You will always be able to reclaim your tokens no matter what happens to any validator.
