Information on latest downtime [ 10/07/2012 - 10/14/2012 ]

Oct 7, 2012

Nagstart po ang problem last October 7. Naging unresponsive yun server ng PINOYDEN inakala namin na may problem lamang yun database or network ng server. So ang ginawa ko triny irestart ang server pero walang effect so inisip ko baka may problema lang ang network connection ng server kaya wala magawa kundi maghintay sa reply ng tech support.

After ilang oras bumalik na ulit yun server. Pero nagloko ulit.

Online na ulit yun server pero hindi pa accessible dahil nag full backup kami ng database. After ilang oras online na ulit yun server.

We checked the server and found out that we are getting a lot of port scan attempts on our server. Di ko pinansin dahil we normally get a lot of these on some of our servers. Pero naghihinala na ako dahil marami kaming IP addresses na nadetect na galing sa bayantel 210.4.15.xxx. 

Should I follow up the IP addresses to find out who is using them at the time when the UDP packets were sent? Baka pwede natin makilala kung sino sya [/i] Nope that would be just a waste of time. I am currently working on DroidVPN with the new design at that time so nagfofocus nalang muna ako sa baging GUI ng app kaysa mag investigate

Saturday around 9PM nagkasunog sa kapitbahay. F**K malaki na ang sunog Kailangan isecure ang laptop at ang aking potpot nagpanic ng konti pero buti nalang mabilis ang mga bombero at napatay ang apoy bago pa matupok ang aming tinitirhan

Naubos ang energy namin sa sunog kaya di ko nalaman na down na pala ang forum siguro yun ay nagstart ng 12:00 AM

Kinaumagahan pag open ng computer yun down ulit ang server :slap: last time ang iniisip namin ay nagkaproblema lang ang network ng datacenter pero sa ngayun ang ibang servers namin sa same datacenter ay online so I am sure na may nangyayaring hindi maganda sa server.

I temporarily redirected the server to a temporary server to show the maintenance page. That's when I found out that the server was being DDoSed because the temporary server started to become sluggish after redirecting our domain.

Our server's IP was then null routed so wala na kaming magawa kundi hintayin na ireinstate yung IP addresses.

Niredirect nalang muna namin sa facebook/blog yun domain para malaman ng ibang users kung ano ang nangyayari.

After ma ibalik ang IP inayos na ulit namin ang server at ayun nga nagbalik na ang PINOYDEN




So in short naging offline ang server ng ilang araw dahil may DDoS attack sa server ng PD. Wala naman tayong malaking fund para ipambili ng Anti-DDoS appliance or mag avail ng Anti-DDoS Service.

We were not able to use cloudflare's service since the main server is already null routed. Aside from that cloudflare cannot actually offer you true DDoS protection especially if the attacker knows what hes doing. It is actually very easy to bypass cloudflare

Hindi namin alam kung bakit nila tinarget ang PD. Para sa akin karagdagang experience ang nangyari pasalamat nalang tayo at nandito parin tayo
