6 days ago we bought a new server in Scranton, PA, US Datacenter (BurstNet) and moved a few sites.
Now we have been receiving a few complaints from some clients from different parts of India that they are not able to see their site. We use MTNL and all the sites are working fine. We checked with a few different ISPs in India (I checked them with AirTel and VodaFone GPRS), they work fine but a few clients are saying that they are not able to access.
Could you please check the following sites and let me know if you can see them fine with your ISP?
I have experienced similar problems before, the problem is not with your server or DC, its with the ISPs here, I have noticed many a times that the same site will load for me using AirTel but will not load for some other AirTel user, so after lot of persuading with AirTel guys it was concluded that it was a fault on their end which they resolved by fixing their router, these ISPs use different routers for different areas and categories so at the same moment site may be loading for some but not for others. And this problem is not just with AirTel most of the ISPs are having the same issue.
So you can ask the client to talk with their ISP support people to resolve the issue.
Did India finally fix that underwater cut cable issue they had a month or so ago? I know I have a client there that has to use his cellphone for Internet access (at least the last time I talked to him).
