Interesting. It looks like somebody tried to deplatform Rumble. The previous IP address (205.220.231.24) stopped working. Rumble has responded by unleashing a bank of IP addresses which they have apparently been keeping in reserve. New IPs are registered to Rumble. The previous was registered to Pathway Networks.
Down detector shows that Rumble was offline but is now working:
