If the MD5 sum of the total .iso is correct than one can be fairly[1]
sure the mirror is perfectly OK
[1] OK, maybe the .es guys broke the MD5 checksum mechanism, and intentionally
put different data in the .iso. But if they really did break MD5,
why didn't they also fix-up the internal md5 checksums?
