the network status forum thread says things are better, but i'm not seeing an improvment.
Hey, what tool are you guys using that generates those nifty % packet lose stats in the text output?
Code:
4 28 ms 28 ms 28 ms 200.ge-0-1-0.cr2.sea1.speakeasy.net [69.17.83.250]
5 29 ms 29 ms 28 ms ge3-0.cr02.sea01.pccwbtn.net [198.32.180.13]
6 101 ms 90 ms 91 ms gnax.ge2-13.br01.atl01.pccwbtn.net [63.216.31.130]
7 90 ms 165 ms 89 ms 63.247.77.6
8 * * * Request timed out.
9 * * * Request timed out.
10 * * * Request timed out.

| We're getting rather slow response from atlanta23.linode.com this evening (and this morning around 0700MST it was also slow). |

I don't know if this helps, but I it seems the routing between my test point and atlanta22 is different than to my linode on atlanta22:
I'm realiably getting 100% loss to my linode on atlanta22:
Code:
10. pr1-so-0-3-0.atlantapaix.sav 8.3% 120 27.1 31.0 22.6 254.8 31.8
11. bpr1-so-1-2-0.AtlantaPaix.sa 0.0% 120 22.7 22.9 21.8 50.8 3.5
12. 216.89.82.82 0.0% 120 22.1 26.9 21.7 202.3 25.5
13. 216.89.82.82 2.5% 120 22.2 26.8 22.0 130.6 17.3
14. 63.247.77.6 53.3% 120 23.0 23.8 23.0 45.9 3.1
15. ??? 100.0 120 0.0 0.0 0.0 0.0 0.0
but not to atlanta22 host linode
Code:
8. sl-bb22-fw-12-0.sprintlink.n 0.0% 120 1.6 11.5 1.5 203.2 33.9
9. sl-bb25-atl-6-0.sprintlink.n 0.8% 120 1.8 23.2 1.6 255.4 44.5
10. sl-st21-atl-0-0-0.sprintlink 0.0% 120 20.0 21.5 18.0 157.9 18.0
11. 207.13.126.74 0.0% 120 20.7 24.4 18.1 189.6 25.5
12. l3-atl-18.gnax.net 0.0% 120 20.1 25.8 19.9 213.7 26.1
13. 63.247.71.217 0.0% 120 20.6 20.8 20.0 41.1 2.3
I've repeated this several times, same results. I have several linodes on atlanta22, same results -- can't reach the linode IP but can reach the host IP. |

(10 linodes on atlanta22, sequentally numbered IPs cuz I ordered em within seconds of each otehr) |

Are you guys doing some funky firewalling? Because I can get to .37 just fine, which is someone else's Linode but would be the same route, and I'm seeing my packets hit your Linode's interface.

| I'm on 64.22.124.245, the dash board shows the host load as low, but http requests are being served dead slow, pings and tracert from my end (137.186.192.1) are timing out. |

| and I don't think I've got any complex firewall settings, just a firehol configuration to allow SSH, HTTP and HTTPS through which has not been modified in a few weeks. |

| I do have some weird firewall rules, but they've been up for months. But that explains the dropped packets at the host. But I'm still experiencing the strangeness reflected by seemingly dropped packets at the upstream router, that .6 router. |

I'm seeing flaky connectivity from host77 @ atlanta at 12:44a central time on dec 8.
My linode isn't mission critical, and I don't want to be one of those whiny people, but it's a little discouraging that we don't seem to be getting close to a diagnosis.
It seems to me that this isn't a linode problem, but rather a data center problem. So maybe the linode guys could start yelling louder at the data center guys?
Thanks... |

| Yeah what I worry about is that the ATL data center people think it's fixed when it's really not fixed. It's good that we keep an eye on this I think, especially since it's hard to diagnose this particular routing problem. |

Can't be the DC, I mean I can ping atlanta21.linode.com from my Freemont linode, and from my linode in Dallas.

The only difference is the last hop which is your linode.
As well though the IPs are in different blocks, so maybe when they swapped out maybe the routing tables got FUBARd.
