leslie, you out there?

ryuu.psg.com:/Users/randy> host links.email.donate.wikimedia.org.
links.email.donate.wikimedia.org is an alias for recp.mkt41.net.
recp.mkt41.net has address 74.121.50.40

   $ dscacheutil -flushcache

does not clear it

this is all in tokyo.  so i ssh into a server in seattle westin.

    psg.com:/usr/home/randy> host links.email.donate.wikimedia.org.
    links.email.donate.wikimedia.org is an alias for recp.mkt41.net.
    recp.mkt41.net has address 74.121.50.40

the real or unreal CNAME RR is pretty prevalent

pretoria

    root at afnog:~ # host links.email.donate.wikimedia.org.
    links.email.donate.wikimedia.org is an alias for recp.mkt41.net.
    recp.mkt41.net has address 74.121.50.40

london starts to scare me

    drinx.linx.net:/root# host links.email.donate.wikimedia.org.
    ;; connection timed out; no servers could be reached
    drinx.linx.net:/root# host links.email.donate.wikimedia.org.
    ;; connection timed out; no servers could be reached

so i look at the nearest zone i can find

    ryuu.psg.com:/Users/randy> doc -p -w donate.wikimedia.org.
    Doc-2.2.3: doc -p -w donate.wikimedia.org.
    Doc-2.2.3: Starting test of donate.wikimedia.org.   parent is wikimedia.org.
    Doc-2.2.3: Test date - Tue Nov 26 10:46:48 JST 2013
    SYSerr: No servers for donate.wikimedia.org. returned SOAs ...
    Summary:

at least the parent is ok

    ryuu.psg.com:/Users/randy> doc -p -w wikimedia.org.
    Doc-2.2.3: doc -p -w wikimedia.org.
    Doc-2.2.3: Starting test of wikimedia.org.   parent is org.

    Summary:

aha!

    ryuu.psg.com:/Users/randy> ns donate.wikimedia.org.
    donate-lb.eqiad.wikimedia.org.

i suspect a load balancer

yes, i reported this to wikimedia two days ago.  a response, then black
hole.  problem persists.
