Having problems with no less than three of my #DigitalOcean instances this morning -- can't get through at all. (Fortunately, the TootCat server seems to be ok.)
Anyone else having DigOc issues?
@woozle Cloudflare is having a major outage. Do DO use CF?
@dredmorbius I'm not sure. They offer CDN as an option, but I haven't used that for any of my servers.
@dredmorbius Looks to be a networking issue. If I ssh into TootCat's server, I can then contact the others by ssh.
@woozle Smells like DNS or routing.
Do the other hosts resolve?
@woozle Network troubleshooting. If any step fails, that's where to start digging further:
ping www.google.comusually establishes this. If not, local host/router/ISP issues.
dig <hostname>If not: DNS issues.
ping <hostname or IP>If not; connectivity.
mtr <hostname or IP>Especially watch for latency, dropped packets (loss), or failure to rech remote, or rapidly changing routing (different intermediary hosts).
wgetshould be useful here, other services as appropiate. Is the server up and responding? Success or error codes?
If all this works but you still have issues, dig further.
I was farmiliar with (and did) steps 1-3; hadn't heard of
mtr before; I always just used
traceroute -- but I didn't think to try it this time (I think Frontier used to make it useless, somehow, so I got out of the habit) and hey,
mtr looks seriously nifty. I've saved that and a link to your list for future reference.
@woozle Neat feature of mtr is that you can toggle display of ASN rather than IP, which helps when BGP is melting down.
