3. STATUS AT THE END OF COPERNICUS 1 
Despite the technical challenges and the high Service Level 
Agreements, the DU achieved significant results during the 
reporting period. The Virtual Infrastructure Availability has 
been always very stable (see Fiaure 6). On the other hand, 
axternal interface availlability has been the real challenge, 
as depending on the integration between Software and the 
data itself, and the actual usage. DU Team spent most of 
the time and evolutions (planned and unplanned) on 
improving this aspect, via different methods as describec 
in previous sections (improvements on backend, software, 
collaboration with PCs, etc) resulting in a constant 
'mprovement of the robustness and general avallability of 
:he Service, as shown in Figure 7 (NRT) and Figure 8 (MY).
