At first, I'm not able to name my question properly, so this will be adjusted
I recently experienced an international network gap. Mean when some part of world wide network is unavailable.
I'm able to find out using ping
,traceroute
,nmap
tools where the gap occurs and where are my requests thrown away or discarded.
example of recent gap:

icmp_echo
gave me request timeout, so I traced the request to 46.249.37.143
(which is my VPS)
This last IP 149.11.38.30
is (according to http://www.infobyip.com/) located in Washington DC, USA. Does it mean, that in Washington, they're blocking traffic to this network node or what?
- First, I wonder, if we can trace to where and who specific IP was allocated
- I tried RIPE DB Query, but I wonder if this is the right way
- I know about reverse DNS query, but this is what
traceroute
does automatically
- Second, If there is any world wide network monitoring system, where we can find out if there is any maintenance or network problem
- I tried RIPE Atlas, where status of some (every? public?) nodes is displayed on map
- Third (from question title), if we can somehow detect why this outage occurred
- If it was some kind of bgp routes change or whatever it can be (I honestly don't know what reasons can be there)
Please excuse my language skills, I'm not sure if everything is laid down correctly and clearly. Ask if anything is unclear. Thanks
