Massive 503 errors

[cheapweb]

using PS 1.6.1.4

 

We have made a new shop recently and its working a bit slow.

 

Also getting a massive amount of 503 errors:

 

8. oktober 2016 17:46:25 503  GET /en/1697-gucci-eau-de-parfume-ii-edp-30-ml.html   66.249.76.39 8. oktober 2016 17:45:27 503  GET /da/   204.187.14.71 8. oktober 2016 17:42:55 503  GET /en/harpleje/falengreen-styling/wax-no-15-75-ml   66.249.76.41 8. oktober 2016 17:41:18 503  GET /en/   204.187.14.71 8. oktober 2016 17:38:05 503  GET /da/content/handelsvilkear   66.249.76.37 8. oktober 2016 17:37:51 503  GET /da/hudpleje/coola/coola-sport-classic-sunscreen-u ..   66.249.76.41 8. oktober 2016 17:34:34 503  GET /index.php?controller=404   207.46.13.184 8. oktober 2016 17:32:22 503  GET /index.php?controller=404   207.46.13.15 8. oktober 2016 17:30:55 404  GET /332-home_default/saebeholder.jpg

As you can see, basically everything I do gives me a 503, but shows the pages though.

 

The 503 errors also deny me the possibillity to test the site with page-testing sites.

 

Can anybody help me fix this?
