2a02:180:6:1::659 has been terribly unreliable the last few weeks. Seems like I'm using the Server :: Webreboot to reboot it every day. Sometimes more often than that!

I'm nearly certain it's the host node that's the problem. I suspect it's overloaded.

My guest isn't heavily loaded at all. In comparison, we also have one of the original beta test instances (2a02:180:6:1::4a8) as well, running about the same mix of stuff, and it's not been nearly as much trouble.

I'd really appreciate it if someone would check the host and see what's going on with it.

Thanks!

Update: it's the network!

I'm running a cronjob that logs the default route and then does a traceroute to an external host.

2022-07-01 04:08:42 UTC: external ping monitor detected the VPS went offline
2022-07-01 11:03:13 UTC: VPS rebooted from control panel

Once it was back up and running, I examined the log.

Here's the last entry before it went offline:

From then on, the log shows that the traceroute failed. This proves the VPS was powered on and running, but it had no network access. The network gateway was replying to pings, but not routing.

Pretty conclusive that the problem is with the gateway, right?

Hello,

you should check your issue at any time from both directions.

[wt-newell]

It's been much better over the last week. Whatever y'all did seems to have helped. Thanks!

BTW, is there a forum for sync and share alpha feedback?
