  Hi David,
  Please check again and confirm that all vessels are properly displayed.

  The problem seems to be in the Dutch Harbor sector. I notice that the times of last position are all thousands of hour out of date and that vessels not in my fleet, Coastal Transportation Inc., don't show at all. I can tell from dock cams that there are vessels present.

  Hi David,

  Do you have the Ad Block add-on installed on your browser by any chance?

  I don't think so because there are plenty of ads showing on most windows. The problem seems confined to Dutch Harbor shipping. Areas like Seattle show hundreds of ships. At Dutch Harbor, I can see two ships in my fleet if I select the fleet option. Their locations haven't been updated for thousands of minutes, yet I know they are there through independent means. When I deselect fleet, they vanish and no other ships are displayed.

  Aha, suddenly all the ships in Dutch Harbor have reappeared. Nothing I did here, I don't think.

  @ David,
  I follow you few days - indeed no activities see Dutch Harbor Alaska - 9:15 Belgian time this morning we see an activity!
  @MarineTraffic
  The AIS source that we see is “ 50 “ for the vessels over there, there are no information coming out for that station and we find them also not back into the list of receiving stations
  Can you look at this?
  Marc

  Marc, I think there must have been a technical problem with your station in Dutch Harbor. This afternoon all the ships in the Dutch Harbor sector reappeared and in correct locations. A few ships I can actually see in live web cams. Thanks everyone for all the help.

  Hi all,

  Marc there are some station IDs in our system that are hidden. Most of them are bi-directional aggregate feeds we maintain with other AIS data providers. In a nutshell they are multiple stations all over the world or over a specific area, packed into a single unified feed. 116, 98, 396 & 50 are a few examples (all hidden IDs).

  It is possible that 50 suffered a temporary issue the past few days.

  Best Regards
