Re: [OSM-talk] More DNS issues with tile.openstreetmap.org (not resolving for me currently)
Hi, Quick, very technical background * openstreetmap.org has 3 NS servers [abc].ns.bytemark.co.uk * tile.openstreetmap.org CNAMES tile.geo.openstreetmap.org (bytemark) * geo.openstreetmap.org has 4 NS servers [abcd].ns.openstreetmap.org * tile.geo.openstreetmap.org is served by a PowerDNS Geo backend, which based on source query IP replies with country code cname eg: gb.tile.openstreetmap.org. ([abcd].ns.openstreetmap.org) * gb.tile.openstreetmap.org replies with CNAME to closest Tile Cache Server eg: amsterdam.tile.openstreetmap.org (bytemark) * amsterdam.tile.openstreetmap.org replies with IP (bytemark) The mistake... A mistake in a deployment script of ours (fixed here: http://git.openstreetmap.org/dns.git/commitdiff/42f905a1a337d4d0ccf0acb5ee0af8acc63df059) incorrectly set the NS servers for geo.openstreetmap.org to [abcd].ns.openstreetmap (note no suffix TLD) with a very long TTL (~54 hours) causing the breakage. Tile traffic is down a few % points and is improving. Yes, there are some hacks we could use to get around the problem (tile2.openstreetmap.org or geo2.openstreetmap.org), but we decided to just wait a little (easier/safer/less-ugly-hack). There are many great alternative maps: * http://tile.openstreetmap.fr/ * http://openstreetmap.de/karte.html * Other layers on openstreetmap.org Regards Grant Part of OSM sysadmin team.

Sorry ignore some of my last mail some of these failed online tools only work on top levels domains (it late *yawn* and I wasn't paying attention) rather than subdomains. Anyway I still get a lookup fail. Maybe it is just my ISP.*shrug* -- View this message in context: http://gis.19327.n5.nabble.com/More-DNS-issues-with-tile-openstreetmap-org-not-resolving-for-me-currently-tp5773835p5773836.html Sent from the General Discussion mailing list archive at Nabble.com. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
[OSM-talk] More DNS issues with tile.openstreetmap.org (not resolving for me currently)
I am now getting DNS failed for I am in the UK using a Vodafone mobile dongle to connect. nslookup gives C:\Users\Rovastar>nslookup tile.openstreetmap.org Server: UnKnown Address: 88.82.13.12 *** UnKnown can't find tile.openstreetmap.org: Server failed C:\Users\Rovastar>nslookup www.openstreetmap.org Server: UnKnown Address: 88.82.13.12 Non-authoritative answer: Name:www.openstreetmap.org Addresses: 2001:630:12:500:219:bbff:fe39:8aba 2001:630:12:500:21a:4bff:fea5:fd2a 2001:630:12:500:219:bbff:fe39:3d9e 193.63.75.103 193.63.75.100 193.63.75.99 My mobile EE is all ok. I have tried a few other online sources I use to check DNS stuff (As I day job for the past 14 years I am/have been a web hosting consultant) CA/just-ping.com and that is ok. http://cloudmonitor.ca.com/en/dnstool.php?vhost=_&vtt=1376692608&varghost=tile.openstreetmap.org&vaction=trace&trace=analyse But pingdoms online DNS check gives errors doesn't even resolve currently. http://dnscheck.pingdom.com/?domain=tile.openstreetmap.org×tamp=1376691983&view=1 (that is historic try again to test fresh) and DNSstuff gives errors in your SOA. http://www.dnsstuff.com/tools#dnsReport|type=domain&&value=tile.openstreetmap.com but resolves. Not all errors mean stuff is completely broken (you have to really understand DNS and your setup to get the best understanding and some complex large global corp DNS infrastuturces can do things in ways that confuse online scanners IBM, etc) but it is for me and may be propagating around to everyone SOA errors often show something broken. I would also a reduce your TTL you have been having (and still are) to less then the current 24 hours until you get to bottom of these issues otherwise the lag on fixing and/or creating more issue will be problematic to solve. I can give you a hand diagnosing if needed. -- View this message in context: http://gis.19327.n5.nabble.com/More-DNS-issues-with-tile-openstreetmap-org-not-resolving-for-me-currently-tp5773835.html Sent from the General Discussion mailing list archive at Nabble.com. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
