I am wondering what some of you guys do when your home ISP is down. At least those of you that don't give yourself internet.
Ooh, heck. I'm going through this at the moment. I noticed a website that doesn't load some of the time. After a bit of digging, I discovered that it doesn't load only when our ISP has given us an address in the 2.97 range, but fine in other more 'normal' ranges. Bit of digging later seemed to confirm that a router 12 hops away in Cogent's IP space (38.*) in Boston is replying with "destination net unreachable", or simply dropping the connection on the floor. So, looks like that router doesn't like previously bogonised IP space. Fair enough. I thought I would actually give this to my ISP to fix, to see what would happen, and used their online tech support forums to do this . I reported it last Tuesday, the 9th of August. Acknowledged on the 11th of August, given an incident number etc. So, this Tuesday they reset the card in the MSAN at the exchange, cutting all phone and Internet for 20 minutes. After a bit more of "the issue is still with Networks", as of today, we've got as far as them asking if I use their DNS servers or someone else's. I've sent them the output of nslookup from their own, OpenDNS and Google, showing the same IP response from all three. We've even had confirmation from another subscriber elsewhere in the country that the same thing happens. So, nine days in, we're still waiting for someone within "Networks" to try and connect to this website themselves from their own IP space; they've still not decided that this issue isn't occurring from the exchange to our house. This ISP has 4.2 million residential subscribers, so is fairly sizable. I'm going to be interested in how long it takes to get to their routing guys. It's going to be enlightening to see what happens. Alex
