      Make sure you have swap available. 2GB isn't terrible, but not quite enough for even a tiny instance to run unimpeded.

      I could definitely jack this up to whatever I want.

      I will also work on getting this up to Fedora 29, I didn't even realize it was still on 27 :face_with_open_mouth_cold_sweat:

      Also, I just submitted a ticket, we'll see what they say.

      I'd add 2GB of swap.

        This. After you reboot, pay attention to the STEAL time. I've never noticed that in the display before... In your glances pic above, steal % is at 48%.
        I had to go google it to see what it was, lol... The short version is that steal % is how long your VM has to wait until the Hypervisor gives it more CPU time.
        This article, though dated, seems to give good info.
        (Understanding CPU Steal Time)

        This almost sounds like I have a noisy neighbor on my VPS?

        always possible, but rarely seen as a CPU spike.

        It is not a spike. it is his system constantly waiting on CPU resources from the host.

          There were 260 failed login attempts since the last successful login.

          I may be getting slammed by script kiddies here too... This is with fail2ban on. My last login was almost exactly 2 hours ago. I will change my SSH port and see if that helps anything.

            Change your login method to use keys instead of U&P. . .

              That's totally normal traffic and not being slammed at all. That's light.

                I usually see that many in a couple hours with fail2ban off, with it on I might see 260 in a week.

                  @bnrstnr i agree with Scott here, that is nothing in terms of attempts. My stuff will get thousands in a few minutes when it happens.

                    Alright, that's good, one less thing to check off my list. Like I said, it's more than I normally see, but I definitely believe you guys. Thanks

                      @bnrstnr How's the client ISP connection? I've seen some major issues at handoff points to Level3 since their merger with Comcast.

                      Comcast? I thought Level 3 was bought by Century Link?

                          I'm more than slightly mixed up apparently.

                            Hello,

It does not seem that any other guests on the host are using an excessive amount of CPU power.

First, I would check your configurations on your running services to see if anything is out of the ordinary. If all seems to be in check, we can migrate your instance to a new host to see if that resolves the issue.

Let us know your findings and how you'd like to proceed.

                              Have em move it and see if that fixes the issue. Nothing in what you've shown seems excessive so make them do some work as a means of troubleshooting.

                                Yeah, it's not like that's going to be more than clicking a button for them.

                                  Can't remember where I saw it but some company with a lot of cloud instances were using scripts that would automatically kill an instance and start it on another server if it started being slow. They found that once it start getting slow it would never recover it's original speed and get back to it's former self so this is how they solved it. You never know what else is running on the same host and how many VMs.

                                  Can you yourself someway force the instance to move to another host on vultr?

                                    There is no web interface for that. I'd be surprised if the API had it.

                                      @scottalanmiller How about if you take a snapshot, then kill the instance and then restore. Will it end up on the same host?

                                      I'm not a vultr user so I'm just guessing here :smiling_face_with_open_mouth:

                                            So, this morning I requested that they migrate my instance to a new host and they came back with this:

                                            Hello,

We have detected a system issue with the node hosting the instances listed above. Our engineering team applied system updates and scheduled a brief maintenance window to perform a node restart. Once rebooted we expect your server performance to return to normal.

Date and Time:

Dec-06-2018 08:00 UTC (Dec-06-2018 03:00 Local Time)

Please note: This event will reboot your affected instances. Your data and configurations will not be affected by the reboot.
