TOKYO, JAPAN, 2000 MAY 8 (NB) -- By Adam Creed, Newsbytes. NTT Communications Corp., the long distance and international operator of Nippon Telegraph and Telephone Corp. (NTT) [TOKYO:9432], says it has signed a definitive agreement to purchase all the shares of US-based Web site and e-commerce hosting company, Verio Inc. {extracted} $5.5 billion over 525,000 domain names the world's largest operator of Web sites for businesses. {/extracted} So, what will it mean operationally?

Probably because the said standards bodies (and on-demand fiber capacity allocation in general) have little relevance to the NSPs and Internet backbones in general? --vadim PS I keep wondering why people keep reinventing virtual circuits.

Optical Crossconnects and IP

** Disclaimer; I work for a vendor: PLURIS, but this question concerns a personal curiosity that I have about OXCs. ** ------------------------------------------------ There has been a lot of work going on about how to utilize OXCs in an internetwork at both OIF and ODSI (and some IDs in IETF). A couple of themes have been emerging: 1. Use the OXCs to set up paths akin to MPLS LSPs. This is great for providers that have MPLS, but what about pure IP-based backbones. 2. Decide which routers connect with what other routers (within the same domain) using configuration. Then use signaling to create circuits between the routers to connect them. I would like to hear about what people are thinking about OXCs, how they are intending on utilizing them, what functionality to they expect from their routers. Let me put in my two cents worth: --------------------------------------------- It is hard not to think of the OXC-based circuit model as another overlay network, but it brings distinct provisioning advantages in terms of speed and flexibility. There apparently are some cost advantages as well. On the other hand, the OXC based optical network is a change in some manner from a converged IP over optical network architecture where IP routers plug directly into DWDMs and have enough ports to handle all of the traffic. For NSPs that have already an MPLS or ATM solution, an OXC-based circuit switched model is not a big leap, but for all IP shops it is. I also don't see much NSP participation in the relevant standards bodies about signaling in optical networks. Thanks in advance Bora Akyol

Australia OPTUS outage investigated (was Re: DACS blamed for MCI / CSX train problems last week)

Some do, compare Worldcom's reliability to Sprint's reliability. Of course, after the merger things may change (FUD, FUD, FUD). But even then you can have more outages than you can handle. For example, Cable&Wireless OPTUS network in Australia experienced dual fiber outages within a couple of hours bringing much of their network down. http://www.newsbytes.com/pubNews/00/148623.html The most reliable network I know about, FEDWIRE, only has 3-5 way diversity. How does the fed assure the carriers actually route the circuits they way they were ordered? I don't know.

DACS blamed for MCI / CSX train problems last week
by Sean Donelan 08 May '00

08 May '00

According to Computerworld, the MCI outage affecting CSX rail lines last week was caused by DACS problems. http://www.computerworld.com/home/print.nsf/all/000505DCCE This isn't the first DACS problem nor is MCI the only carrier affected by DACS problems. Bell Atlantic had a multi-day DACS problems, I've experienced 18+ hour MCI DACS problems in the past. What is it about DACS systems which seem to lead to such catastrophic problems? How can you put an entire train system out of operation due to a single piece of equipment?

Alert timeline for Love Bug
by Sean Donelan 07 May '00

07 May '00

Senator Bennet from Utah wants to know where the FBI was when the "Love Bug" began circulating through e-mail systems in the USA. I thought I would try to figure out when various different alerts first reached the public from various sources. Although there may be some "private" alerts earlier, I don't have a good way to find out their timestamps. I've tried to normalize all times to UTC. 4-May-2000 10:17 UTC NANOG posting 4-May-2000 12:54 UTC AP (Hong Kong) 4-May-2000 13:17 UTC Reuters(London) 4-May-2000 13:30 UTC ZDNet News 4-May-2000 13:31 UTC F-Secure press release 4-May-2000 14:30 UTC Financial Services Information Sharing Alert 4-May-2000 14:30 UTC CERT/CC Alert 4-May-2000 14:38 UTC Symantec press release 4-May-2000 15:00 UTC FBI/NIPC Alert 4-May-2000 15:05 UTC Computer Associates press release 4-May-2000 16:19 UTC Trend Micro press release I think the FBI did pretty well. In context, the FBI alert came out approximately the same time as most commercial virus vendor press releases. I'm not surprised NANOG beat the FBI or CERT by 4 to 5 hours. But I think I missed some news reports. Does anyone know of any verifiable public alerts or news stories about the "Love Bug" before 1017 UTC?

Only one gave me solidly useful clues: All the traces were n.*...the * being various VisualBasic-related extensions. The one that gave me useful info was n.log - showed the modem log and dialout times, etc, but not a list of what was transmitted. The number the modem dialed was XXX'd out; and the transmission stats showed the 10megs. The end user confirmed that, although he was doing some VB6 programming for a class, it wasn't his script and that no one was home at the time the dialout occured. Unfortunately, the system was unstable as hell and I was lucky to get this data before it crashed completely; W98 wouldn't load at all because of (suspected) corrupted files. Before it crashed completely (and the reason the end user called me) was that upon W98 boot, a system error would be displayed saying RPCSS.dll had caused a GP fault in OLE32 and then a VB debug session would start and freeze. The other encounter showed similar symptoms but left no clues that I could find. >Virus_Research(a)NAI.com, samples(a)f-secure.com, and support(a)sophos.com >all are addresses where suspect files can be sent.
