Here is my BGP analysis, based on the data archived as part of
http://www.multicasttech.com/status/
I know of only one fiber landing station in Burma, in Pyapon with
service from SEA-ME-WE 3 :
http://www.sintelsat.com/fibernetworks/SEAMEWE3.html . There has been
discussion in Bangladesh with installing fiber to link their landing
station in Cox's Bazar with Pyapon, but I don't think that that is
there yet. I believe that there is also only one satellite landing
station.
Here is some technical info. AFAIK there are 2 autonomous systems in
Burma :
9988 MPT-AP [DS72-AP]
{43, Boaung, Yangon, Myanma, MM} Myanma Post and Telecommunication
18399 BAGAN-TRANSIT-AS [KS220-AP]
{Union of Myanamr, MM} Bagan Cybertech IDC & Teleport
International Transit
I dump and archive all BGP data here every 6 hours, so I can go back
into the past.
Before September 27, 2007, these ASN reached me via the following AS
paths
AS 9988 MPT-AP as path 174 3491 9304 9988
AS 18399 BAGAN-TRANSIT-AS as path 174 2914 9988 18399
That is to say
Cogent <-> CAIS <-> Hutchison Telecom (HK) <-> MPT-AP
Cogent <-> CAIS <-> MPT-AP <-> BAGAN-TRANSIT-AS
(Note that CAIS has more than one autonomous system number.)
Both of these BGP announcements were shut off between
Sep_27_18:07:00_EDT_2007
and
Sep_28_00:07:00_EDT_2007
and have mostly remained off since.
At 0600 EDT for 2 of the days since, there has been different
announcement from 18399
AS 18399 BAGAN-TRANSIT-AS as path 174 3549 9731 18399
that is
Cogent <-> Global Crossing <-> STTP-AS-SG-AP <-> BAGAN-TRANSIT-AS
where STTP-AS-SG-AP is ST Teleport Pte Ltd - Multihomed and Transit
AS - Internet via Satellite Service Provider,
2B/2C Ayer Rajah Crescent, Singapore 139937.
I saw these on
Sep_28_06:07:00_EDT_2007
Oct_1_06:07:00_EDT_2007
and not since. I would guess this was a satellite link.
On
Oct_1_18:07:00_EDT_2007 only I saw
AS 9988 MPT-AP as path 174 3491 9304 9988
which is to say the original path.
Given the 6 hour sampling, I have to assume that there have been
other short term re-appearances of routes to Burma.
Whether this is due to internal struggles, accidents, or urgent needs
for data transfer I cannot say.

There have been several news stories today about Myanmar's
government turning off the country's Internet connectivity to
suppress news coming out of the country (for instance: http://
www.nytimes.com/2007/10/04/world/asia/04info.html?ref=world). Doing
some poking at it earlier today, here's what I found:
The .MM top level domain has disappeared. It's served by three name
servers:
;; AUTHORITY SECTION:
mm. 172800 IN NS NS-MM.RIPE.NET.
mm. 172800 IN NS NS.NET.mm.
mm. 172800 IN NS NS0.MPT.NET.mm.
;; ADDITIONAL SECTION:
NS.NET.mm. 172800 IN A 202.153.125.17
NS0.MPT.NET.mm. 172800 IN A 203.81.64.20
NS-MM.RIPE.NET. 172800 IN A 193.0.12.151
ns0.mpt.net.mm is in Myanmar, part of the network of Myanma Post &
Telecommunication. It's unreachable.
ns.net.mm is in address space registered to Powerbase DataCenter
Services (HK) Ltd. in Hong Kong. It's also unreachable, which
makes it difficult to confirm whether its physical location matches
its registered location. It may also be in Myanmar.
ns-mm.ripe.net is in Amsterdam. It's reachable, but is responding
to all queries with a SERVFAIL response. Presumably, this means it
hasn't been able to get updates from a master server for the .MM
domain for long enough that its data has expired.
Looking at the rest of Myanmar's connectivity to the outside world,
Myanma Post & Telecommunication has two IP address blocks
registered to it: 203.81.64.0/19 and 203.81.160.0/20. Both of
those blocks were in the global Internet routing table on September
27, but but have not been since September 28 (according to daily
snapshots of route-views data). It's pretty safe to say that
Myanma Post & Telecommunication has completely turned off its
connection to the outside world. This is no doubt following the
example set by the King of Nepal during the coup there a couple
years ago.
The New York Times story says there are two ISPs in Myanmar.
Myanma Post & Telecommunication is the only one with IP addresses
registered to a mailing address within the country, so I'm not sure
who the other one is, or what its status is.
