Subject: DNSSEC resolution failure for the "مصر" TLD (xn--wgbh1c)

The "ﻢﺻﺭ" (xn--wgbh1c) IDN ccTLD has a DNSKEY RRset (algorithm 13) which does not match its root zone DS RRset (algorithm 8).  This makes the entire TLD zone invalid from the perspective of DNSSEC validating


This appears to have been the case for some time now:


and earlier dates show expired algorithm 8 signatures:


While it is nice to see an apparent rollover to algorithm 13 in progress, course the DS RRset needs to include the new algorithm (13) before the RSA keys for algorithm 8 can be dropped from the zone apex.

Though at this point likely easier to replace the root zone DS records with matching algoritm 13 data.
