This is affecting all my nodes inside BurstNet. |

I tested it from 2 locations and it seems okay to me. Pings go through without any packet loss. Did you open a ticket cause they will be here in 3 minutes asking for a ticket number. |

We are experiencing an issue with one of our 10G circuits between Scranton and Philadelphia.
We are aware and are looking into the issue with the circuit provider, but have no ETA at this time.
You may experience some packet loss and delay while we work on this issue.
Thank You
P.S. it was four minutes

Thanks, much appreciated. |

I am also having a bunch of issues accessing burst.net's network.
But my issues seem to be coming from another hop. The 209.197.18.22 hop seems to be the problem. It has very high ping spikes and some packet loss. I'm not sure if this is related or not. Some confirmation would be nice. Thanks!

Ditto. Seeing a lot of problems at xe1-01.agg01.sctn01.hostnoc.net ... been going on for a few hours now. Sigh. |
| Posted by RedTechie, 05-24-2011, 01:00 AM |
This is absolutely crazy... It's been like this all day. In addition to the massive packet loss sessions; we must of been completely dropped from our servers 30 times now!
I have a support ticket going but they keep saying nothing is wrong.  Even after giving them tons of trace routes, pathping's, and ping's all from different sources.
Very very frustrating especially when your trying to get new clients setup on the same servers! |
| Posted by BurstNET_CSM, 05-24-2011, 08:34 AM |
As we said, there is a problem with one of the 10G circuits that connects Scranton to Philly. It's our provider's issue and there's nothing we can do but remind them that this is affecting our customers.
Right now it seems it is dropping the connection every four hours or so, which is causing timeouts and packet loss. We ARE doing what we can (As noted above, however, it's nothing we can actually fix ourselves). |
| Posted by RedTechie, 05-24-2011, 09:15 AM |
BurstNET_CSM: Thanks for the update on the issue! This makes me feel slightly better that you are aware of this problem. As the tech's in the ticket I have created keep telling me there is no problem.
Question: To verify, the 209.197.18.22 hop is related to this particular connection issue? |

Can you PM me the ticket where you were told this, please?

I will ask out networking team. |

BurstNET_CSM: The forum keeps saying I don't have permission to send you a PM. The ticket ID is 2694323. |
| Posted by BurstNET_CSM, 05-24-2011, 10:48 AM |
It's because you have 0 posts. You need 10 posts to be able to send PM's.
Thanks. |

BurstNET_CSM: Were you able to verify that the hop in my previous post is involved with this problem? |
| Posted by RedTechie, 05-24-2011, 06:46 PM |
I believe there is a routing loop going on.
I pinged the hop before 209.197.18.22 which is 209.197.18.18 I got the following:

So we increased the hop count for this IP to 255...and what do you know I got a result with very high latency (normal latency should be around 30ms for me):

We then tried to test for a routing loop using "tracert -w 500 209.197.18.18" we got the following:

Although this last test seems to be intermittent where it sometimes produces this looping result. |

Sorry for the multi-posts. I would edit my previous post but the forum won't allow me to do that either.
Here is more proof that there is a routing loop:

Notice that every other hop gives me a TTL expired. Out of the hops that give me the "TTL expired" I get a reply from either 209.197.18.22 OR 209.197.18.17 stating that the TTL has expired. |
