Computer data at the Colombo Stock Exchange go missing

Computer data at the Colombo Stock Exchange go missing


The breakdown in the computer system at the Colombo Stock Exchange (CSE) on the 20th has resulted in the loss of many confidential data stored in the system, sources from the CSE said.

Transactions at the CSE came to a standstill on the 20th following the breakdown in the computer system.


A fine of Rs. 10 million had been made before the breakdown in the computer system for failing to provide details of a private company. The usual fine for such an offence is around Rs. 100 million. It is now being discussed at the CSE whether the breakdown in the computer system occurred with the knowledge of a senior government member due to the loss of many data.

Ah! manipulators lata wada loku magodiyak wenna yanne!

I wonder what kind of people work at their IT department...aren't they have any back up system.
at least a external HDD or DVD?

They have backup systems.
I think the people who created this news have no background knowledge about a computer system.

back up system ekath corrupt athi! back up karata back up unadha kiyala check karanawadha?

What a shame. What they are doing with our commission money. playing casino??

This is reticules. this is not a small office in slave island,should have involved more professionalism than this

This is I think we should not easily take as casino. Its more than that. When I checked this morning my accont statement last year it gave me wrong figures.Luckily I had perssonal notes on my transaction. However in the evinining its ok. situation is very very risky.

Happy to see your after some silent days!

Now I found who published this story first.

It is from lankanewsweb - a well known mada website . Their main job is creating and publishing various news against out motherland. Their technique is find a small incidence and fabricate a big story around it.

Hence credibility of this news is very low.

Any important database system have backup methods 1D, weekly, monthly ... etc. in different physical locations. I cannot think the developers of the systems for CSE did not follow these basics. After all we are the masters of Trading platforms in this Universe. ( Millennium IT - create and control CSE, LSE (london SE), Egypt SE, Trans European ... ... many other exchange systems all over the world)

Breakdown of a trading system due to hardware or software failure is one thing. Any loss to backup databases and other data at CSE is another thing. That is why I suspect this could be a creation of a laymen who do not know the structure of a computer system.

Somehow I have no direct info at the moment.

Record no of accounts at CDS, ever increasing commissions for these institutions.If they can update there systems,something wrong there. yea its serious

I don't know much about this problem. I asked it from cse but they didn't provide a useful answer.

Its very serious one day halt of trades and data loss

I think they don't care about that. They try to hide something from other people. We have to find that.

Only possible way is inside action. A top person who has all the security keys may do it purposely. Traceable- who did it. Still recoverable.

I suspect what actually happened was erasing 1 days data due to burning of a chip.

As per my memory, they created the system faster than the hard-disk access speed to facilitate 1000s of transactions per second. For that RAM (memory) formed as a virtual hard disk and data is saved in the RAM disk to achieve the speed. They are saved in the real hard disks later.

Hence there is a possibility of loosing current days data due to a hardware failure.

How can this happen? It's hardly unlikely. They have an IT department and they have hired dedicated DBAs to maintain the databases. They should have taken over night full backup and differential backup in regular interval to recover the database in a critical failure. On 20th September, they didn't do a point in time recovery. They just restored the full backup taken on the previous day. That's why they have rolled back all the transactions happened during morning hours.

If the data is still missing then it's one of the major crime and DBA team should take the fully responsible.

Note: Monster is currently working as a DBA

I never believe that any data is missing .MIT is one of the best and I do not think they have lost back up data too.
If we think about the political situation, our country is still driven by many mad persons.I don't think I should name some of them because we all know.
Now the president has instructed CSE to take immediate actions to restore a manipulated free market.

what MIT ? Is that the best software company in the world ?
Look at SLC. SL is 1 time world champs and two times runners up. They saved all the valuable data only to one hard disk. Just before the audit hard disk is missing. What a great management and great future planning. If they had saved data to two disks, loss would be double.

OK. I'm a bit suspicious on the whole CSE hardware down scenario;

CSE, I guess, is a place where at grass root levels be equipped with cluster servers and SAN systems if we thought of the minimal criteria for an exchange system to function properly. I mean, if it doesn't have this, OK its just a crazy thinking

Now a clusters means at least 2 servers and SANs means an array of storage.. Clusters even have their own level of redundancy; 2 or more power supplies, etc.. So does a SAN..
So at this level, it has basic level of redundancy, hence to fail, either the full cluster system has to fail or if data is corrupted, the entire SAN array has to fail..
U cant shutdown a system cuz they have backup UPS power

So how a hardware failure has happened? Somebody switched off both servers? he hee..

That's de little knowledge I have.. I may be wrong..

Questions that need answers:

- Why did that happen?
- When was the last DRP conducted?
- What prevented the Backups being restored?
- Where were the backups stored?
- What time were the backups scheduled to be taken?
- Isn't there another location in case of system failure?
- Are the staff trained in DRP?
- Is there a BCP in place? (Business continuity Plan)
- Who are the key staff involved in the BCP?
- Is there a Crisis Management Team in Place?
- Are the heads of all these teams still working?

These few questions will help in trouble shooting and coming to the root cause of the failure.

Computer piracy and hacking is all over the web. It's fun for some hackers but it's serious business for those who are in charge of web security. We were hit by few of those attackers few days ago.. We Survived!

I too look in the same line as ' Small ' on this matter. The servers are not placed in open spaces. but in special rooms with Access control systems. The 2nd clustered server is in another location which takes over server functions once the 1st one fails.

In such a case it is not possible to switch both servers at the same time by a unauthorised person. Assuming that the worst possible failure they should have in place a fully documented and tested DR plan . And in a hour or so the full system is to restored in to live mode.

I feel there is a failure in implementing the DR plan .
