Fedora 29 is being released today. That means Fedora 27 hits its End of Life (EOL) status on November 27th 2018.

After November 27th 2018, packages in the Fedora 27 repositories will no longer receive any security, bugfix, or enhancement updates. Furthermore, at that point the community adds no new packages to the F27 collection.

The FedoraForum highly recommends you upgrade all systems to Fedora 29 or Fedora 28 before the EOL date. Upgrades are an easy way to keep your system setup while you move to the latest technology.
