Gzip/DEFLATE Disabled in CGI Web-Space?

I just made some changes to my web-site and ran the GTMetrix test on a page for the first time in a few weeks.  I noticed that my score had decreased; the reason being that Gzip compression wasn't enabled.
I'm pretty certain that it used to be, and I've checked my .htaccess file (and even tried some alternatives), and everything seems to be OK.  Does anyone know whether this feature has been disabled on the servers?  Obviously a lot of users now have mobile devices, so I'm not happy about my pages getting three times bigger.

When was the last time you checked?
Edit: Although glancing at some old phpInfo() output I can see:
HTTP_ACCEPT_ENCODING 	gzip, deflate

Isn't that from the request headers and not the configuration?
The request headers I send (according to Apache) include
Accept-Encoding: gzip, deflate

but GTMetrix suggests a need to "Enable gzip compression". (on the server)

Listed under 'Environment' and 'PHP Variables'. You're right that it's not listed as a module.
Andrew, if you raise a support ticket, we can ask the question of Hostopia if you like?

Thanks for the replies - I'll try a support ticket; it might be an oversight, I suppose.
I'm pretty sure that it was working earlier this year.  I did some tests for "mobilegeddon", checking that my site was mobile-friendly in the eyes of the new Google algorithm, so it was probably around that time.  GTMetrix was showing full marks for everything except "Using a CDN" and "Using a cookieless domain", and PageSpeed Insights was also giving me a higher score than it does now.  I'm not sure what the cookies are for, either, but they don't seem to have a big impact.
I was wondering whether they'd upgraded Apache and there was a newer syntax, but the code in my .htaccess file comes straight from the Apache site.

I've finally had a reply to my question - it seems that mod_deflate was disabled for security reason.
