Packages for debian-8.8.0-amd64-netinst.jigdo are missing on fallback mirrors

["Thomas Schmitt" <scdbackup@gmx.net>]

Hi,

a thread on debian-user reveils problems with package mirrors for 8.8.0
jigdo images. It begins at
  https://lists.debian.org/debian-user/2018/02/msg00531.html

Rick did not show all 8 file URLs. To see are 3 more than the above one:

http://us.cdimage.debian.org/cdimage/snapshot/Debian/dists/jessie/main/installer-amd64/20150422+deb8u4+b3/images/netboot/debian-installer/amd64/grub/x86_64-efi/multiboot.mod

http://us.cdimage.debian.org/cdimage/snapshot/Debian/dists/jessie/main/installer-amd64/20150422+deb8u4+b3/images/netboot/debian-installer/amd64/grub/x86_64-efi/http.mod

http://us.cdimage.debian.org/cdimage/snapshot/Debian/dists/jessie/main/installer-amd64/20150422+deb8u4+b3/images/netboot/debian-installer/amd64/grub/x86_64-efi/multiboot2.mod


This time it does not look like no-matching MD5s but rather like flatly
missing URLs.

The .jigdo file has as flabback servers:
  [Servers]
  Debian=http://snapshot.debian.org/archive/debian/20170506T140911Z/
  Debian=http://us.cdimage.debian.org/cdimage/snapshot/Debian/ --try-last


Have a nice day :)
