Hi Mark,
thank you for the very informative post! In the meantime, our own provider moved some routes from GTT to...Cogent and the times decreased within the normal range. Also a few VPS providers such as EdgeNext are using NTT & Cogent and show no issues either. So it seems some providers experience an extra 80ms delay for some reason, I wonder why. This is our new traceroute
Yeah - best thing to do would be to reach out to a problematic provider and ask them for an explanation. Usually, if they have bought directly from a subsea provider, then restoring from a subsea outage may be complex depending on how well they secured themselves both from a diversity and capacity standpoint. If they are a customer of a major transit provider, then their provider's subsea inventory situation is similar to my point above. It is very hard to tell unless you ask someone on the inside, but as these things do, when cables get cut, latency and packet loss increases are not unexpected, especially for small/local/regional ISP's that can't afford to have direct access to multiple subsea systems. And in cases where alternative options are either too costly or non-existent, the latency and packet loss penalty would be sustained longer than necessary. Depending on where you are in the food chain, subsea restoration efforts following a major cut can increase normal pricing by 3X - 5X, particularly if the restoration capacity is taken on a short-term basis, e.g., 3 months.
