probe offline - troubleshooting requested
by Andre Heinrichs 18 Oct '16

18 Oct '16

Last night my probe (#29384) was declared offline after the daily Internet disconnection my FritzBox executes to keep the provider from disconnecting me after 24 hours online. According to the SOS history the probe gets DNS requests out but somehow fails to connect completely. I tried rebooting every network component i could locally get my hands on but that didn't seem to help much. The LEDs on the probe don't actually fit any of the descriptions from the FAQ: They are On, Off, fast(er) blink (at least if compared to shortly after booting (Network Test?), On, On. I'm guessing it means the network somehow managed to fail. Although I don't notice anything missing from what I did on the network this morning. Any ideas what I could try to get the probe reconnected? Just to be complete: Here are the last lines of the SOS history: 62.109.121.35 2016-10-18 05:43:27 A 3h 59m 62.109.121.35 2016-10-18 05:43:27 AAAA 3h 59m TIA, Andre, currently not in reach of the probe

Shall we continue non-public measurements in RIPE Atlas?
by Mirjam Kuehne 18 Oct '16

18 Oct '16

Dear colleagues, "Non-public measurements" is a feature of RIPE Atlas that allows users to use the infrastructure to measure things while not sharing those results with the public. Is that still a useful feature? Should it exist in the future? For more details, see this new post on RIPE Labs: https://labs.ripe.net/Members/kistel/non-public-measurements-in-ripe-atlas Please also take the polls at the end of the article. Kind regards, Mirjam Kuehne RIPE NCC

Temporary Reduction of Available History on RIPE Atlas and RIPEstat
by Romeo Zwart 18 Oct '16

18 Oct '16

Dear colleagues, Today, Tuesday, 18 October 2016, between 09:00 and 10:00 UTC, the back-end storage cluster for RIPE Atlas and RIPEstat will be switched to a backup environment. This is part of planned maintenance work. The backup facility has a more limited amount of storage space, which means that RIPEstat and RIPE Atlas, including specific applications like DNSMON and DomainMon, will not serve data older than one year. We expect this to have no impact on ongoing RIPE Atlas measurements, scheduling new measurements, or the retrieval of more recent data from RIPE Atlas, RIPEstat or DNSMON. We apologise for any inconvenience. Kind regards, Romeo Zwart

Problems with f.root-servers.net in Russia?
by Marat Khalili 18 Oct '16

18 Oct '16

Sorry for slight offtopic, but does anybody know what is up with Russian instance of F root server? I observe periods of very high packet loss since 11th of October. I used to measure my own internet connectivity pinging it, but seems like by internet works better than that of the root server. Here's a measurement with 50 Russian probes, 34 of them show "Unreachable" right now: https://atlas.ripe.net/measurements/6886549/#!probes -- -- With Best Regards, Marat Khalili

Out of date system probe tags
by Chris Amin 17 Oct '16

17 Oct '16

Dear all, Some of you have noticed that certain system tags (see below) remained applied to probes when they should have been removed. This is because the process that adds and removes these tags was temporarily disabled following the service issues that we experienced earlier in the month. This process has now been re-enabled after verifying that it was not a cause of the service downtime, and these tags have been applied correctly. The affected tags were: * Flaky connection * Firewall problem suspected * DNS problem suspected * No flash drive * Readonly flash drive * Hardware problem suspected Kind regards, Chris Amin RIPE NCC

Connect/disconnect timestamps on probe page disappeared
by Marat Khalili 13 Oct '16

13 Oct '16

Connect/disconnect timestamps on a probe page like https://atlas.ripe.net/probes/26656/#!tab-network disappeared this morning; durations still shown. Probably some problem with server side scripts? -- -- With Best Regards, Marat Khalili

firmware download test?
by Yang Yu 12 Oct '16

12 Oct '16

Hi, I have 2 probes that are connected but shown as offline even after several power cycles. I performed USB stick troubleshooting procedures by removing the USB stick and saw NO-USB SOS message. But after inserting the USB stick there wasn't any new SOS messages. Plugged the USB stick to computer and saw corrupted file system. Formatted the stick and inserted it back, still no SOS messages. What kind of filesystem layout is expected on the stick? From what I read the probe should automatically partition/format the stick. Maybe the stick is bad. I do see a good amount of packet loss between the probe's network and the registration server. How robust is the firmware download process (e.g does it abort on TCP RST)? Is there any way to manually load the firmware? Thanks. Yang
