I am experiencing a similar issue. My `yum-hourly.cron` is returning constantly:

```
/etc/cron.hourly/0yum-hourly.cron:

Updateinfo file is not valid XML: <open file
'/var/cache/yum/x86_64/7/epel/92f2e15cad66d79ea1ad327e2af7af89d98e4d153d7a3e27ff41946f476af5b4-updateinfo.xml.zck',
mode 'rt' at 0x7f57b1eb2270>
```

In the server if I run `yum updateinfo summary all` I get:

```
[...]
(10/10): epel/x86_64/primary_db

and running `yum update` yesterday I would see:

```

```
if I run `yum update` now I get:

```

```
Is the mirror down currently because it is being fixed?


Everything seems to work fine if I edit the repo in `/etc/yum.repos.d/epel.repo` and use
the `baseurl` instead of the `metalink`:

```
[epel]
name=Extra Packages for Enterprise Linux 7 - $basearch
baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch
#metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch
```
