SixXS's tunnelrobot complains about downtime

Shadow Hawkins on Saturday, 16 May 2009 03:16:11

User: PV3595-RIPE Tunnel-ID: 19396 (2001:6f8:900:c40::1/64) Tunnel-Type: static If I could trust in the tunnel statistics the PoP deham01 went down on Thursday 14th May at 5 pm. As far as I know the PoP is up again since around Friday 15th May 09:30 CEST. Yesterday evening, I wondered that I have not earned 5 ISK for tunnel uptime. OK, this may happen if the PoP was down for a long time. I also wondered that the static graphs didn't get updated. On Sat, 16 May 2009 01:16:19 +0200 (CEST) I've received an email from the tunnelrobot:

This is the tunnelrobot at SixXS, mailing you to inform you that your tunnel to Easynet has not been replying to pings for a period of time Here's the information regarding the tunnel: ...

In the log (https://www.sixxs.net/home/log/) I've found this record:

2009-05-16 01:16:19 | Tunnel endpoint 2001:6f8:900:c40::2 didn't ping for 2 days | -5

For me the tunnel seems to be reachable: Ping from Tunnel-ID 18558:

Problem resolved. (Can't fix things while in an Airplane and having no connectivity unfortunately... other "me too comments" all marked hidden. Really, when a ticket is filed we will see it and act upon it ASAP, which is now that I have connectivity again. Request Queue will be resolved tomorrow after I have had sleep again, ISK will be refunded then too)
