Yeah... hard to do though.  Any ground helps.  I used to do telco NIDS 
(actually we called them protectors back then) with #12 or #14 back in the day. 
 I think #10 for an Ethernet surge protector is adequate.  I know various 
regulatory authorities etc want a #6 it just is not practical to do for small 
devices.  They treat a small surge protector the same as a power entrance 
ground.

Telecommunication cable metallic shields shall be bonded to the site’s 
grounding electrode system as
described herein. Where outside facility telecommunication cables are 
configured for a standard
entrance, the metallic members of all incoming telecommunication cables, 
including paired-conductor
and optical fiber cable, shall be grounded (earthed) to the MGB, either 
directly or through a SSGB at
the facility’s entrance point. Each metallic member shall be effectively bonded 
to the grounding point
with a 16 mm2 csa (#6 AWG) or coarser green-jacketed grounding conductor, or 
with a transmission
line ground kit, using bonding methods described within this chapter.

So they say #6 AWG. 

I'm an unqualified rando on the internet, but I'd say if you grounded it with 
anything at all then you did better than most.

  Whats the smallest gauge stranded ground i can use to bond bbdge copper 
shield to the ground lug on surge suppressors? Ive been using #8 but it gets 
cumbersome in a 12 port cross connect enclosure, i dont have footprint for a 
larger enclosure and my contractors hate my design
