Hi there, There are some sites that are being blocked by ISPs here in India. The two cases I checked are, 1. mega.nz 2. t.me In some cases, It's the Consumer ISP that's blocking access to these domains and in other cases it's the upstream providers like Tata(AS17908) that are blocking access to these sites. To figure out how many probes were effected, I ran 2 TLS tests. The results of those tests are here, 1. https://atlas.ripe.net/measurements/32358061/ 2. https://atlas.ripe.net/measurements/32358052/ As you'll see that almost every probe received correct TLS Certificate with mega.nz and excluding 4-5 probes, All the other probes received correct certificates for t.me. These measurements include 2 probes that I run in AS9829 and AS45609. Somehow, Both of my probes reported that they received the correct/valid certificate in both of these measurement when it doesn't appear to be true. I am presented with connection closed error when accessing these sites over HTTP and a connection reset error when accessing these sites over HTTPS over both WANs used by the two probes. Have I misunderstood TLS tests? I am not sure what is happening here and I really appreciate any insight I can get on these results. I have also included the relevant section from the logs of 1 of my probes. atlas_run: looking for 'evsslgetcert -4 -p 443 -h mega.nz -A "32358061" 66.203.127.18' eooqd: found cmd 'evsslgetcert' for 'evsslgetcert -4 -p 443 -h mega.nz -A "32358061" 66.203.127.18' eooqd: atlas_run: argv[0] = 'evsslgetcert' eooqd: atlas_run: argv[1] = '-4' eooqd: atlas_run: argv[2] = '-p' eooqd: atlas_run: argv[3] = '443' eooqd: atlas_run: argv[4] = '-h' eooqd: atlas_run: argv[5] = 'mega.nz' eooqd: atlas_run: argv[6] = '-A' eooqd: atlas_run: argv[7] = '32358061' eooqd: atlas_run: argv[8] = '66.203.127.18' eooqd: atlas_run: argv[9] = '-O' eooqd: atlas_run: argv[10] = '/var/atlas-probe/data/new/ooq.2' eooqd: init returned 0x738200 for 'evsslgetcert -4 -p 443 -h mega.nz -A "32358061" 66.203.127.18' eooqd: check_resolv_conf2: no change (time 1632496526) msgbuf_read: buf_read failed ooqd: command is done for cmdstate 0x738200 sslgetcert_delete: state 0x738200, index 0, busy 0 total size in dir: 5982 httppost: before getaddrinfo httppost: before connect httppost: sending request posting file '/var/atlas-probe/data/out/ooq/2' httppost: getting result httppost: getting reply headers httppost: got line 'Server: nginx' httppost: got line 'Date: Fri, 24 Sep 2021 15:56:32 GMT' httppost: got line 'Content-Type: text/plain' httppost: got line 'Transfer-Encoding: chunked' httppost: got line 'Connection: close' httppost: writing output httppost: chunked 1, content_length -1 httppost: got chunk line '3' httppost: chunk data 'OK Regards Ishan Jain
