Hello,
I will try to keep it short. Since a while ago we are facing issues from our customers to connect to our service at yclas.com you can read more about it here.
We have different servers but the one having issues is at OVH French region and only customers who use AT&T in the US are facing this issues.
We have fixed it so far using cloudflare, but all the subdomains can not be added to cloudflare since there’s some limitations…
We have contacted AT&T and OVH , they do not answer us and we only have their forum….seems they have a problem on their DNS.
OVH so far not any answer and without fix…anyone having this same issue?
Pro Tip
If you need to check if your site can connect using an AT&T connection you can use this service:
From your command line:
ssh rviews@route-server.ip.att.net
Use as password rviews
Then launch the treaceroute:
traceroute 91.121.25.98 traceroute to 91.121.25.98 (91.121.25.98), 30 hops max, 40 byte packets 1 gateway203.cbbtier3.att.net (12.0.1.203) 0.793 ms 0.789 ms 0.933 ms 2 * * * 3 * * * 4 * * * 5 * * * 6 * * * 7 * * * 8 * * * 9 * * *
Et voila! not working 🙁
Update: Actually their site is not accessible either.
