Some files intermittently fail, seems to depend on which server is used.
It seems that some files intermittently fail. Looking more closely it seems whether or not they fail depends on which server is used (snapshot.debian.org seems to have multiple a records). For example.

So it looks like 193.62.202.30 is successfully serving the file while 185.17.185.185 is failing.
Could someone take a look at what is different between the two servers?
