| I have several hosts with Vultr (kvm-based I believe), one of which is now oddly slow. | |
| Right after a reboot, things are working fine but just 12 hours later, sending five pings take 35 seconds: | |
| $ time ping -c5 localhost | |
| PING localhost (127.0.0.1): 56 data bytes | |
| 64 bytes from 127.0.0.1: icmp_seq=0 ttl=255 time=0.360 ms | |
| 64 bytes from 127.0.0.1: icmp_seq=1 ttl=255 time=0.124 ms | |

| --- localhost ping statistics --- | |
| 5 packets transmitted, 5 packets received, 0.0% packet loss | |
| round-trip min/avg/max/std-dev = 0.079/0.150/0.360/0.106 ms | |
| 0m35.50s real 0m00.00s user 0m00.01s system | |
| Interactivity via SSH becomes prone to unusable spikes of latency. Loading files via HTTPS seem unaffected. | |
| Sending pings from another host shows it's responding just fine. I've seen time being off by 3-4 hours as well. | |
| Any input? |
