Thanks! I see the same thing you do with gnutls-cli, so i can confirm
this as an issue with their servers. I see those connection failures
even with the priority string NORMAL:+%COMPAT :(
FWIW, i can get connections to work with both of the above using the
following priority string:
That is, it looks like these two servers sending fatal alerts to any
client that advertises support for TLS1.1 or TLS1.2 :(
They both negotiate to TLS1.0, though.

that 6.0 was released with Windows Server 2003, and superceded by IIS
7.0 with the release of Windows Server 2008. I'm a little surprised to
see www.microsoft.com running such an old version on their flagship web
site. other MS sites (e.g. technet.microsoft.com) are using IIS 7.5 by now.
I'm not sure the right way to deal with this from GnuTLS is. Should we
be doing anything differently to accommodate these non-compliant servers?
