http://pl.archive.ubuntu.com/ stopped syncing

[Tomasz Makarewicz]

It looks like official Polish mirror of repository stopped syncing with the main repository at the beginning of February 2017. It seems to be serious problem, as all Polish users are left without any updates (even security). The address of the repository is:
http://pl.archive.ubuntu.com/

Ping says that pl.archive.ubuntu.com points to ubuntu.task.gda.pl which indeed does not seem to be in sync with main server.
Some other Polish mirrors, like ftp.icm.edu.pl seem to be up to date.
So the problem is with some mirrors having issues with syncing with main server.

I'll try to contact with task.gda.pl administrator to get some info about this issue.

It's working again.
