It's a bit suspicious that it would break in two places at once. There was a panic in 2015 about Russian ships and submarines supposedly placed to be able to cut cables. You can imagine the havoc they could cause if they carried that out, perhaps combined with destroying a few satellites.
Adding to that, the two cables are constrained by having the same endpoint and needing not-too-steep paths through the same landscape on the ocean bottom.
Reminds me of planning cables in a "backhoe safe" pattern out of a building so a single backhoe can't take out all of your connectivity in a single incident.
Yeah, it's most likely a normal failure. I only said "a bit" suspicious. I suppose it will takes weeks to get a cable ship out to Tonga to fix the breaks. Oh, a comment elsewhere says not so long.
