Serverdragon down

Serverdragon seems to be down. Their Controlpanel, Client Area, Frontpage are not accessible, from either my connection, my VPSes, or with http://www.downforeveryoneorjustme.com/serverdragon.com.

Was there some planned downtime? Afaik, they are not located in LV with Fiberhub.

Edit: Got hold of their twitter-account:

seems to be just the router config.

  • From Twitter:

    Wrong configuration file loaded on primary router. Failing over to backup router.

    Source:

  • Yep, my VPS with SD is down as is their web site.

    Lol, this sucks, my primary NS is at SD and my secondary NS is at BuyVM. :(

    @KuJoe is probably aware, but this post should ping him too.

    Same here, my two US VPSes are with them. And both are down now. Bad luck.

  • Yeah, I sorta freaked out when my VPN stopped working and I couldn't access their site, solusvm or client portal. Then I pinged my Florida DNS server and got scared when my other server, on a totally different node was down.

    Joe will sort it out though. =]

    And that's why you need to have at least 3 nameservers, it almost never happens but it happens.

  • @vedran said: And that's why you need to have at least 3 nameservers, it almost never happens but it happens.

    3 everything if possible

  • Or just use rage4.com for DNS. They have like 20 servers around the world.

  • Third DNS - LocalISP.

  • @rds100 said: Or just use rage4.com for DNS. They have like 20 servers around the world.

    Where's the fun in having someone else do it? ;)

  • Or have 8 nameservers. Because I like Nameservers

  • Lol I spun down my third NS last month during a migration to powerdns, after a year of no serious outages on any of the three. :(

  • @ivanfilippov Murphy is teaching you a lesson then ;-)

    Anyone care to write up a LEB tutorial on setting up redundant NS with, say, 128MB of RAM?

  • @zhuanyi said: Anyone care to write up a LEB tutorial on setting up redundant NS with, say, 128MB of RAM?

    I personally use cPanel DNS Only and that requires at minimum 256MB of RAM.

    To my knowledge DNS servers should have a minimum of 256MB.

    You can always setup your own cluster of Webmin.

    I'm not too used to it but I do know some people use PowerDNS

    I can only suggest to use a low-mem daemon such as nsd

  • @HalfEatenPie said: To my knowledge DNS servers should have a minimum of 256MB.

    Why that? Maradns runs fine with on a 32MB VPS.

  • @japon said: Why that? Maradns runs fine with on a 32MB VPS.

    Oh. I've actually never used MaraDNS and if that works then great (obviously I was more focused on DNS servers that are compatible with cPanel and other similar services, which obviously are memory hogs).

    A general rule of Thumb I go with is bind and NSD need minimum of 256MB (may be a waste of resources, but all of my DNS servers are on 1GB RAM VPSes).

    Bind yes, NSD no :) NSD can serve hundreds of domains in a few MB of RAM. A 32MB VPS works just fine.

    Oh. Well you got me there then.

    This has been dis-proven countless times here.

    Back online. Eff DDOS mitigation software and eff BGP. :(

    Failed over to the backup router normally without issues. Then I tried repairing the primary router and caused our DC's routers to not want to establish a BGP session with us. While trying to fix the primary router the backup router started working again out of nowhere for no reason. I hate Murphy.

    Well, I think you cant have it much worse than Francisco and the gang. After finally almost everything in place, power decides to take a break a few times...

  • It's still down...

  • Down again.

    twitter down as well?

    nm... I need coffee

  • Down again :/

  • It's one of those days...

  • KuJoeKuJoe Member, Host Rep

    This makes no sense. While rebuilding the primary router for the 2nd time our network went down again. I powered off the primary router but our backup router is not coming back up although all DDOS Protected IPs are online still which also makes no sense. God I hate networking so much. :(

  • @KuJoe sounds like the protected ips announced by CN head home to you via a GRE tunnel, and your issue is more with bgp and your /22's ( Dampinfo: penalty 1297, flapped 15 times in 00:48:58, reuse in 00:00:54 )

    No idea how you're set up, but if you're stuck and need a hand pm and I can try to help.

    Is BGP Sessions setup on the backup Layer 3 Switch/Router? If not that is probably why.
