Aircraft
We were setup on the ILS 27 approach into BOS. They were also landing 33L. The Final Approach controller issued us maintain 170 kts to RIPIT (FAF) during the approach we received Red X's 3 times which would indicate the Localizer isn't working on our instruments. This happened outside the FAF and we were visual and could maintain a visual with the airport that we decided that we wouldn't go around because it was VMC. We continued the Approach. Final asked what speed we were doing. I replied 170 kts. He then came back and said spacing wouldn't work and even if we slowed it wouldn't work. Cancel Approach clearance turn right 360 and maintain 2000 and that he would sequence us back. My Captain then replied over the radio 'Unable we were given red x's and we are having navigational problems.' After a few seconds the Captain then said 'we broke out we need to continue the approach' (we were already visual). Final says traffic to look out for 11 o'clock 800 ft. Captain replies traffic insight. Final says maintain a visual with the traffic cleared ILS 27. I then repeat back maintain visual and clear for the approach. Final asks if we were having issues with navigation. I reply we are visual with the airport. Final hands us off to tower. This whole exchange lasted for over 30 seconds from when he asked how fast we were going until we got the hand off to tower. We were 3.6 DME from the ILS when the other aircraft landed. The red X's appeared around 13.5 to 11.5 DME. Upon taxiing in ground had a number for the captain to call. The captain called the number and then after some time referred the guy to our chief pilot I wasn't able to hear what the whole conversation entailed I just heard what the Captain said to the person.
Air carrier First Officer reported navigation problems arose on final to BOS Runway 27 and they continued to a visual landing after ATC had cancelled their approach clearance due to traffic to Runway 33L.
