i have had this problem a couple of times now and i am not sure what is causing it

Failed to start apache : .: 45: Can't open /etc/apache2/envvars

when i look at a dir listing, i get these question marks next to envvars, does anyone know what that means?

os is ubuntu 10 if that helps

UPDATE Just heard back from the hosting company, they move my VPS to a new hardware node last night, and something at their end wasn't quite right which caused the issue
