yum update gone bad today?

[sean]

yum has worked for months. It worked yesterday. Now:

  yum update
Repository development is listed more than once in the 
configuration
Setting up Update Process
Setting up repositories
http://download.fedora.redhat.com/pub/fedora/linux/core/development/x86_64/repodata/repomd.xml: 
[Errno 4] IOError: <urlopen error (2, 'No such file or 
directory')>
Trying other mirror.
Cannot open/read repomd.xml file for repository: development
failure: repodata/repomd.xml from development: [Errno 256] 
No more mirrors to try.
Error: failure: repodata/repomd.xml from development: [Errno 
256] No more mirrors to try.


Tried yum-2.5.0-5 and yum-2.4.1-3. Same result.

  cat yum.conf
[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=fedora-release
tolerant=1
exactarch=0
retries=20

[development]
name=Fedora Core $releasever - Development Tree
baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/development/x86_64
mirrorlist=http://fedora.redhat.com/download/mirrors/fedora-core-rawhide
enabled=1


I can pull up 
http://download.fedora.redhat.com/pub/fedora/linux/core/development/x86_64/repodata/repomd.xml 
in firefox.

And it doesn't seem to try the mirrors.

Something changed about yum configuration I've missed?

Any  one else seing this?
