What Caused The Amazon Web Services Failure?
This article on Reuters is entitled Amazon’s AWS Struggles To Recover After Major Outage Disrupts Apps, Services Worldwide, sums up today’s big news story.
But what went wrong?
I asked Google AI, where BT have their data servers and received this reply.
BT hosts its data servers in various locations across the UK, including London, Birmingham, and Dublin, Ireland, as well as in mainland Europe such as Frankfurt, Germany, and Amsterdam and Nieuwegein, Netherlands. They also have a presence in the United States, with facilities in locations like New Jersey.
Note.
- Nieuwegein is South of Amsterdam.
- There’s almost a direct straight-line route between Dublin and Frantfurt.
- Cambridge would lie on that straight-line route.
- BT’s Research at Martlesham in Suffolk would lie on that straight-line route.
- Is BT’s worldwide network closely monitored from BT Research?
- For more about BT Research read their Wikipedia entry.
- The straight-line route by-passes London.
The network seems comprehensive and well spread-out.
These are my thoughts.
The Value Of Research
I asked Google AI, if there were any spin-out companies from BT Martlesham and received this reply.
Yes, spin-out companies have been formed from BT’s Adastral Park research facility, including Real Time Content (RTC) and iome. Both companies were supported by BT and developed technologies based on research from the Martlesham site, with RTC focusing on personalized video services and iome providing location-based services through mobile internet.
I used to live near to BT’s Research Centre until 1990.
At the time, I was writing Artemis, the project management system and the multi-user version of that software and a BT research computer system used the same Hewlett-Packard hardware and an operating system written by BT at Martlesham.
Because of this connection, I learned a lot about their methods and the breadth of the research being carried out in Suffolk and was generally impressed.
I would suspect that legacy telecom companies like BT, France Telecom and Deutsche Telecom spend a lot of money on research. Do newer companies spend similar amounts?
Having a good research department behind you is an excellent form of insurance!
Will BT Research Have A Reliable 24/7 Power Supply?
Consider.
- By 2030, there will be upwards of 4 GW of offshore wind power along the Suffolk coast.
- Sizewell B will be 22 miles away, pumping out 1.2 GW until at least 2035.
- Sizewell C could be pumping out 3.3 GW from the mid-2030s.
- The 1.8 GW LionLink between Walberswick in Suffolk and The Netherlands could be in operation by 2030.
I am fairly sure that BT Research will have enough power, even if several data centres are built on the Martlesham site.
The Domain Name Res0lution Problem
Consider.
- The root causeof Amazon’s disaster appeared to be problems with its domain name resolution system.
- Executing fast lookup of domain names is critical.
I had a similar problem with the project management system ; Artemis, when I extended it to be one of the first relational databases in the 1980s. So I went to IBM’s library on the South Bank and dug out all their 1950s papers on looking up keys in tables.
In those days, with slower computers, which had smaller amounts of memory, the efficiency of the algorithm was very important and I got a significant improvement in look-up speed, by digging up ideas from the past.
If anybody wants to check out their algorithm with me, I’m always happy to oblige, but at 78 with poor eye-sight I’m probably past coding anything myself.
When I was dealing with BT Research, they would have made sure that something like domain name resolution was given the full research treatment.
My Conclusion
As I don’t have all the data, I will not speculate, but will await Amazon’s conclusion with interest.
